Question

The measure of an angle is 7.9º. What is the measure of its complementary angle?

Answer 1

82.1

Explanation:

Complementary angles are two angles the add up to 90 degrees, so if one is 7.9 degrees, then the other has to be 82.1 degrees to add up to 90 degrees. HOPE THIS HELPS!!!

Answer 2

Two angles are called complementary when the sum of their measures is 90°.

That is:

7.9 + x = 90°

x = 90-7.9

x = 82.1°

The measure of its complementary angle is 82.1 °C.
