Question

Which equation can be used to find the measure of the angles below if line a is parallel to line b?

A. 5x - 54 + 3x + 16 = 180

B. 3x +16 = 180

C. 5x - 54 = 3x + 16

Answer 1

I think the answer is c

Answer 2

C. 5x - 54 = 3x + 16

Explanation:

These angles are alternate interior angles and their measurement is same

5x - 54 = 3x + 16

5x - 3x = 16 + 54

2x = 70 divide both sides by 2

x = 35
