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

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!

The equation used to measure each angles is 2x + 3x - 15 = 180.

What is a supplementary angle?

'Supplementary angles are those angles that sum up to 180 degrees.'

According to the given problem,

The sum of angles that are supplementary = 180

⇒ 2x + 3x - 15 = 180

⇒ 5x - 15 = 180

⇒ 5x = 180 + 15

⇒ 5x = 195

⇒ x = 39

Hence, we can conclude, the equation used for measuring the angles is 2x + 3x - 15 = 180
