She needs to know the length of each side so she can buy fencing. What is the length of line segment FJ

Answers

Using the Pythagorean theorem, the length of line segment FJ is: 42 ft.

How to Apply the Pythagorean Theorem?

To find the length of line segment FJ, we need to apply the Pythagorean theorem to find the length of the segment from F to the point, say point O, on FJ where a right triangle FOG will be gotten.

Thus, we have:

FO = √(GF² - GO²)

FO = √(30² - 24²)

FO = 18 ft.

FJ = FO + GH

Plug in the values

FJ = 18 + 24

FJ = 42 ft.

What is angle of elevation?

Angle of elevation can be defined as the angle formed between a horizontal line and the line of sight up to an object with the image of the object located above the horizontal line.

It is the height greater than the height of the observer.

The opposite of the angle of elevation is the angle of depression which is formed with an observer

Identify m∠EFH.

The figure shows triangle G F H. Angle G is equal to 76 degrees. A measure of angle H is given by the formula 3 times x minus 3 degrees. Side G F lies on ray G F with endpoint G. Angle H F E is an exterior angle and its measure is given by the formula 8 times x plus 8 degrees.

Answers

Based on the calculations, the magnitude of m∠EFH is equal to 112°.

How to find the magnitude of m∠EFH?

In Geometry, the sum of two (2) non-adjacent interior angles in a triangle is equal to its exterior angle. Thus, we have:

(3x - 3) + 76 = 8x + 8

3x + 73 = 8x + 8

73 - 8 = 8x - 3x

65 = 5x

x = 65/5

x = 13.

From triangle GFH, we have:

m∠EFH = ∠F = 8x + 8

m∠EFH = 8 (13) + 8

m∠EFH = 104 + 8

m∠EFH = 112°.

Answer:

Step-by-step explanation:

You are given an angle and the length of the side adjacent. You want to find the length of the side opposite, so the relevant trig relation is ...

  Tan = Opposite/Adjacent

Setup

The height of Yuri's balcony is the sum of the heights of Kim's balcony and the height of Yuri's balcony above that. Each of those height is the side opposite a given angle in a right triangle. These can be found by solving the tangent relation for the opposite side:

  Tan = Opposite/Adjacent

  (Adjacent)(Tan) = Opposite

  height of Kim's balcony = (30 m)tan(40°)

  height above Kim's balcony = (30 m)tan(20°)

__

  height of Yuri's balcony = height of Kim's + height above Kim's

  height of Yuri's balcony = (30 m)tan(40°) +(30 m)tan(20°)

  height of Yuri's balcony = (30 m)(tan(40°) +tan(20°))

Evaluation

  height of Yuri's balcony ≈ (30 m)(0.8391 +0.3640) ≈ 36.092 m

The height of Yuri's balcony is about 36 meters.

What is the angle at a

Answers

Answer and Step-by-step explanation:

We are given a triangle, a quadrilateral inside a triangle. and exterior angles of the triangle at linear bisectors.

We can figure out the interior angles of the shape to find a by using the linear bisector theorem, in which a line separated by another line will have two angles that will add to 180 degrees.

For the bisected line with the angle of 60 degrees, the other angle will have to equal 120. We know this by taking 60 from 180.

The perpendicularly bisected line will always have 90 degrees for the angles, so the interior angle will be 90 degrees.

For the bisected line with the angle of 80 degrees, the other angle will have to equal 100. We know this by taking 80 from 180.

Now, we have angles to determine a.

Quadrilaterals consist of 4 interior angles, which, when added together, equals 360 degrees.

360 - 90 - 100 - 120 = a

260 - 90 - 120 = a

140 - 90 = 50 = a

So, angle a is equal to 50 degrees.

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values. Z-score is measured in terms of standard deviations from the mean. If a Z-score is 0, it indicates that the data point's score is identical to the mean score.

for x = 700

Z score =x - μ/σ

P-value from Z-Table:

P(560<x<700) = P(x<700) - 0.5 = 0.44009

for x = 600

Z score =x - μ/σ

P-value from Z-Table:

P(560<x<600) = P(x<600) - 0.5 = 0.17164

If f(-1)=-21,f(0)=-9,f(1)=3,f(2)=15 then the inverse of function f(x) is p(-21)=-1,p(-9)=0,p(3)=1,p(15)=2 which is option d.

Given that f(-1)=-21,f(0)=-9,f(1)=3,f(2)=15 and we are required to find the inverse if the function.

Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.

The given function is as under:

f(-1)=-21,

f(0)=-9,

f(1)=3

f(2)=15

In the inverse of the function the value of x becomes the value of y and the value of y becomes the value of x. So the inverse of the function is as under:

p(-21)=-1,

p(-9)=0,

p(3)=1,

p(15)=2

Hence if f(-1)=-21,f(0)=-9,f(1)=3,f(2)=15 then the inverse of function f(x) is p(-21)=-1,p(-9)=0,p(3)=1,p(15)=2 which is option d.

given a line with slope m then the slope of a line perpendicular to it is

How does the graph of g(x) = (x − 2)3 + 6 compare to the parent function of f(x) = x3?

Answers

The graph of g(x) is the graph of f(x) translated 2 units to the right and 6 units up.

How does the graph of g(x) compare to the one of f(x)?

Here we have:

[tex]f(x) = x^3\\\\g(x) = (x - 2)^3 + 6[/tex]

You can notice that if we take f(x), and we shift it 2 units to the right, we have:

g(x) = f(x - 2)

Then if we apply a shift upwards of 6 units, then we have:

g(x) = f(x - 2) + 3

Replacing f(x) by the cubic parent function, we have:

[tex]g(x) = (x - 2)^3 + 6[/tex]

So we conclude that the graph of g(x) is the graph of f(x) translated 2 units to the right and 6 units up.

What is an inequality?

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the provided data in the question,

The height of the shortest student is 155 cm and,

The height of the tallest student is 190 cm.

It means that the height rage is starting from 155 cm and ending at 190 cm.

Interpret the results. design an algorithm to find the lengths of the shortest paths from s to all other vertices in g in o(|v | |e|) time 1) Consider the following demand curve for good X which is produced by Firm 1 and 2:Price= 100-2*Q1-Q2The cost function for firm 1 is:Total Cost = 2*Q1^2and the cost for firm 2 is:Total Cost = 3*Q2^2A- If both firms agree to work together and maximize joint profits it would result in a market price of ______B- If both firms competed with each other, it would result in a market price of ____________. To answer your question assume the following "best response" functions.Q1 = (100-Q2)/8Q2 = (100-2*Q2)/8 which of the following is most likely to occur if the amphibians become a limited source of food To implement a relationship in SQL we use the reference constraint in CREATE TABLE command. True or False Calculate the area of the surface S.S is the cap cut from the paraboloid by the cone z=9/164x^24y^2 by the cone z=x^2+y^2 What ethical considerations does Mayo Clinic take into account when using technology in healthcare? Classify the statements based on whether they describe characteristics of background extinctions or mass extinctions. Background extinction Mass extinction Answer Bank a sharp reduction in the biodiversity of Earth within a short period of geological time the extinction with a significantly lower rate of species loss the extinction rate used as an estimate of the number of species expected to become extinct each year the extinctions known as the Big Five the result of normal evolutionary processes a departure from the normally occurring extinction rate the extinction rate used as a base of reference Sophia prefers to stick to her routine. she always eats oatmeal for breakfast and is always in bed by 10. Sophia is low in what?a. openness to experience b. extroversion c. neuroticism d. agreeableness 1) What is the amount of heat absorbed by 500 g of water when it's heated from 15 C to 38 C? (The specific heat of water is 4.184 J/g C)2) What is the standard entropy change for the reaction below at 25 C, given the following entropy values? S(H2(g)) = 131 J/mol K; S(Cl2(g)) = 223 J/mol K; S(HCl(g)) = 187 J/mol KH2(g) + Cl2(g) -----> 2 HCl(g) classify the statements as true or false. h for an endothermic reaction is positive. answer h for an exothermic reaction is positive. answer How many times as intense is the sound from a 120 dB sound (band practice) compared to a 100 dB sound (chain saw)? D1 D2 = 10 log ( I1 / I2 ) college students routinely underestimate the amount of time it will take them to complete assigned course projects. this best illustrates the impact of _____
