Question

Two angles are supplementary. One angle measures 2x, and the other angle measures 3x - 15. Which equation can you use to find the measure of each angle? 2x + 3x - 15 = 90° 2x - 3x - 15 = 180° 2x - 3x - 15 = 90° 2x + 3x - 15 = 180°

Answer 1

The answer is D

Explanation:

Supplementary angles add up to be 180 degrees, so you put the two angles together equal to that

Answer 2

2x+3x-15=180°

Explanation:

When two angles are supplementary, their angles would equal to 180° total when added together. In this answer, the two angles are added together to create 180°.
