Answer 1

Answer:

14. y=10

Step-by-step explanation:

3y-7=23

   +7   +7

3y=30

----  -----

3       3

y=10

Answer 2

Answer:

y=10j=8

Step-by-step explanation:

[tex]3y-7=23[/tex]

Collect like terms and simplify

[tex]3y =23+7\\3y=30[/tex]

Divide both sides of the equation by 3

[tex]\frac{3y}{3} = \frac{30}{3}[/tex]

Simplify

[tex]y=10[/tex]

How to find the slope for (2,2) and (-1,2)

Answers

Answer:

Slope = 0

slope is the same as gradient, so you will use the formula

M = y2 - y1 / x2 - x1         in this case (2,2)          and (-1.2)

    the first 2,is x1.then the other 2 in the first coordinate is y1 , for the last coordinate -1 is x2 and 2 is y2, use the formula I gave you , you will see that the answer is 0

Answers

Answer:

1st pic:

x = 61

left angle = 125 degrees

right angle = 55 degrees

2nd pic:

n = 14

left angle = 78 degrees

right angle = 102 degrees

Step-by-step explanation:

1st pic:

use the following equation ⇒ 2x + 3 + x - 6 = 180

combine like terms ⇒ 3x - 3 = 180

add 6 on both sides ⇒ 3x - 3 + 3 = 180 + 3 ⇒ 3x = 183

divide both sides by 3 ⇒ [tex]\frac{3x}{3} = \frac{183}{3}[/tex]

x = 61

solve the angles by subtituting 61 for x

left angle = 2x + 3 ⇒ 2 x 61 + 3 ⇒ 125 degrees

right angle = x - 6 ⇒ 61 - 6 ⇒ 55 degrees

2nd pic:

use the following equation ⇒ 4n + 22 + 8n - 10 = 180

combine like terms ⇒ 12n + 12= 180

subtract 12 on both sides ⇒ 12n + 12 - 12 = 180 - 12 ⇒ 12n = 168

divide both sides by 12 ⇒ [tex]\frac{12n}{12} = \frac{168}{12}[/tex]

n = 14

you can find the angles by substituting 14 for n:

left angle = 4n + 22 ⇒ 4 x 14 + 22 =78 degrees

right angle: 8n - 10 ⇒ 8 x 14 - 10 = 102 degrees

The value of tan60° is ______ . * 1 point 1/√3 0 1 √3

Answers

Answer:

Therefore, the exact value of Tan 60 degrees is √3. We can also derive the values of tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way

The value of tan 60° is √3, approximately 1.732.

To calculate the value of tan 60°, we need to use the trigonometric function tangent. Tan 60° represents the ratio of the length of the side opposite the angle to the length of the adjacent side in a right triangle with a 60° angle.

In a 30°-60°-90° right triangle, the length of the opposite side opposite the 60° angle is equal to the square root of 3 times the length of the adjacent side.

The length of the opposite side is √3, and the length of the adjacent side is 1.

Using these values, we can calculate the value of tan 60°:

tan 60° = (opposite side) / (adjacent side) = (√3) / 1 = √3.

Therefore, the value of tan 60° is √3, approximately 1.732.
