Question

Two angles are supplementary with one angle having a measure of 30 degrees, what is the measure of the other angle

Answer 1

Supplementary angles are defined as angles that add up to 180°.

180° - 30° = 150°.

The other angle is 150°

Answer 2

Answer: 150

Supplementary angles are two angles that add up to 180 degrees.

Since we know one of the angles is 30 we can subtract that from 180 to get 150.
