what is the value of x given the following image

The angles are supplementary, so x + 5 + 2x -8 = 180. Solve for X. I distributed 2(x -4) to get 2x - 8.

3x - 3 = 180
add 3 to both sides
3x = 183
divide by 3 to both sides
x = 61

Angle B is 120°

Step-by-step explanation:

Since it's a supplementary angle (angles that add up to 180°) on top of the triangle, you would find ∠B by subtracting 180 by 60 and ∠B will be 120°. Hope this helps:)

what is the decimal multiplier to increase by 75%

Answers

Answer:

1.75

Step-by-step explanation:

Let the number to be increased be x

If x is to be increased by 75% then the result after the increase T may be expressed as

T = x + 75% * x

T = x + 0.75x

T = 1.75x

As such when x is increased by 75%, the result is the product of x and 1.75 (the multiplier).
