The required values of u = 21° and v = 2 units in the given triangle.

A triangle is a closed shape composed of three angles, three sides, and three vertices. It is one of the most fundamental geometric forms and is represented by the symbol Δ.

The triangle is given in the shown figure, as follows:

We have to determine the value of u and v

In ΔHGF,

∠G = 67°

∠F = 92°

As we know that the sum of interior angles is always 180 degrees in the triangles.

So, ∠u + ∠G + ∠F = 180°

u +  67° + 92° = 180°

u + 159° = 180°

u = 21°

We can see that the bisector HF divides into equal parts EF and FG.

So, EF = FG

This means v = 2

One gallon equals 16 eight ounce glasses of water.

According to the EPA, conventional shower heads utilize 2.5 gallons of water each minute. For the normal shower, that’s 20 gallons of water! To help lower your water impact, try trimming three minutes off your shower time. Delivering, purifying, and boiling hot water for your shower also consumes a lot of energy.

To determine the average shower water use, multiply the average flow rate of 2.1 gallons per minute by the average shower time of 8.2 minutes. So, 17.2 gallons is the average amount of water utilized. A 10-minute shower will consume 21 gallons of water. The amount of water consumed in the shower may quickly add up.

The total area of the two triangles is 3 sq units + (-1 sq units) = 2 sq units.

The equation of line a b is y = 2x + 4

and the equation of line d c is y = x + 4

Substituting the y-coordinate of point E, (6) in the equations of line a b and d c, we get:

2x + 4 = 6

x + 4 = 6

Solving the above equations, we get x = 1 and y = 6.

Therefore, the coordinates of point E are (1,6).

The length of side a b is 9 - (2x + 4) = 9 - (2(1) + 4) = 3

The length of side d c is x + 4 - 6 = 1 + 4 - 6 = -1

The length of side a e is 2x + 4 - 6 = 2(1) + 4 - 6 = 2

The length of side d e is x + 4 - 6 = 1 + 4 - 6 = -1

Therefore, the area of triangle a b e is 1/2 (base x height) = 1/2 (3 x 2) = 3 sq units

The area of triangle d c e is 1/2 (base x height) = 1/2 (-1 x 2) = -1 sq units

Therefore, the total area of the two triangles is 3 sq units + (-1 sq units) = 2 sq units.

When writing a number greater than or equal to 1 in scientific notation, the exponent of the power of 10 will be positive.

In scientific notation, a number is represented as a coefficient multiplied by a power of 10. For example, the number 12,000 can be written as 1.2 x 10⁴ in scientific notation.

When the number is greater than or equal to 1, the coefficient will be greater than or equal to 1 and less than 10. The exponent of the power of 10 will indicate the number of places the decimal point must be moved to the right to get the original number.

Since the number is greater than or equal to 1, the decimal point must be moved to the right, resulting in a positive exponent. So, when writing a number greater than or equal to 1 in scientific notation, the exponent of the power of 10 will always be positive.

The volume of the step and the surface area of the steps are 120000 cm³ and 26,400 cm² respectively.

What is a Rectangular Prism?

A rectangular prism is a three-dimensional shape that consists of six faces. The two faces are at the top and bottom and the other faces are lateral faces.

The given steps can be divided into 3 rectangular boxes each with length, l = 1 m = 100 cm, width, w = 20 cm, and height, h = 20 cm.

The volume of a rectangular box = l × w × h

= 100 × 20 × 20

= 40000 cm³

Volume of 3 rectangular boxes = 3 × 40000 cm³

= 120000 cm³

Surface area of a rectangular box = 2 (lw + lh + wh)

= 2 [(100 × 20) + (100 × 20) + (20 × 20)]

= 2 [2000 + 2000 + 400]

= 2 [4400]

= 8800 cm²

The surface area of 3 rectangular boxes = 3 × 8800

So on solving the provided question, we can say that  A line segment's midpoint is the location where it is divided into two equally sized halves.

The midpoint of a line segment is known as the midpoint in geometry. The centroid of all segments and ends, it is equally spaced from each of them. Add the two figures together and divide by two to determine the middle of any range. Look at this illustration to see how to determine the intersection of two points on a 1D axis. Consider the numbers 5 and 9 as the two points on a number line. Calculating the midpoint is as follows: (5 + 9)/2 = 14/2 = 7. As a result, 7 lies halfway between 5 and 9. There are instances when you need to locate a precise spot between two other points. The term "midpoint" refers to this center. The point on a line segment that divides the line is considered to be the midway of the segment.

A line segment's midpoint is the location where it is divided into two equally sized halves. The point splitting the line segment in any desired ratio can be found using the more potent section formula, which builds on the previous method.

Let's consider an equilateral triangle ABC with a side length equal to 'a'.

Now, draw a perpendicular from vertex A to side BC at point D of the triangle ABC. The perpendicular in an equilateral triangle bisects the other side.

Triangle ABD and ADC are two 30-60-90 triangles. Both the triangles are similar and right-angled triangles. Hence, we can apply the Pythagoras theorem to find the length AD.

[tex](AB)^2 = (AD)^2 + (BD)^2[/tex]

(a√3)/2 = AD

AD = (a√3)/2

BD = a/2

AB = a

180 - (3x-1)°           (sum of angles on a straight line)

180 - 6x°              (sum of angles on a straight line)

180 - 5x°              (sum of angles on a straight line)

Since the sum of the interior angles of a quadrilateral is 360°. We have:

180-(x+16)° + 180-(3x-1)° + 180-6x° + 180-5x° = 360°

180 - x - 16 + 180 - 3x + 1 + 180 - 6x + 180 -5x = 360

To determine the number of biking outfits Rashon can buy while staying within his budget, you can set up an inequality using the information provided.

First, calculate the total cost of the reflectors and gloves:

3 reflectors × $10.78 + $32.64 = $38.34 + $32.64 = $71

Then, subtract the cost of the bicycle, reflectors, and gloves from Rashon's budget: $780 - $481.28 - $71 = $227.72

Now, you can use this remaining amount to determine the number of biking outfits Rashon can buy.

Let x be the number of outfits he can buy

You can set up an inequality as follows:

What is a linear equation ?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form

Ax + B = 0

e.g. x-10=0. Here, x is a variable, A is a coefficient and B is constant.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Now,

As we can see from the graph that for values of y and x

y increase 3 points when x increase 5 points
