Two angles are complementary.
One of the angles has a measure of 20°
.

What is the measure of the other angle?

A ray extends from an angle to create 2 angles. 1 angle has measure 20 degrees and the second angle has measure question mark.

m ∠a + 100° = 180°
m ∠a = 80°

b = 180° - a - 50°
b = 180° - 80° - 50°
b = 50°

The measure of the other angle is 70°.

Explanation:
Complementary angles add up to 90°. Since one angle has a measure of 20°, its complement must have a measure of 90° - 20° = 70°.
