Two angles are supplementary. One angle measures 2 x , and the other angle measures 3 x - 15. Which equation can you use to find

the measure of each angle? 2 x + 3 x - 15 = 90° 2 x - 3 x - 15 = 180° 2 x - 3 x - 15 = 90° 2 x + 3 x - 15 = 180

The last one because supplementary equals 180. and the other one The second one doesn't make sense with its equation.

Supplementary angles add up to 180 degrees so you would take the 2 angles and add them together and set it equal to 180.

2x+3x-15=180 (Option 4)

Hope this helps!
