Question

A figure displays two complementary angles. If one of the angles has a measure of 78°, what is the other angle measure?(1 point) Responses 39° 39° 12° 12° 102° 102° 168°

Answer 1

Complementary angles are two angles whose measures add up to 90 degrees. If one angle measures 78°, you can find the other angle by subtracting 78° from 90°:

90° - 78° = 12°.

So, the measure of the other angle is **12°**.
