Question

The measure of an angle is 99.5°. What is the measure of its supplementary angle?

Answer 1

80.5°

Explanation:

If the sum of any two angles is 180°, then they are called supplementary angles.

Let other angle = 'x'

x + 99.5 = 180°

Subtract 99.5 from both sides,

x = 180 - 99.5

x = 80.5°
