Question

What is the degree measurement for the acute angles? Show all work and justify, in words, why you were able to do the calculations you did to find the angle measurements.

Answer 1

3x=5y times 7x=7=49

Explanation:

Answer 2

14

Explanation:

The acute angles are equal to each other, therefore the equation 3x+5=7x-7 can be made

3x+5=7x-7 solve for x to find the measurement of the angels

-3x -3x

5=4x-7

+7 +7

12=4x

x=3 now substitute x with 3

3x+5 would be 3(3)+5 and 7x-7 would be 7(3)-7

because the angles are equal though, you only need to solve one to get your answer

3(3)+5

9+5
