Question

The measure of an angle is 12.1°. What is the measure of its complementary angle?

Answer 1

Answer: 77.9°

Explanation:

Complementary angles are angles that, when added together, equal 90°.

So to find the complementary angle of an angle that measures 12.1°, you subtract:

90-12.1 = 77.9°

Answer 2

complementary mean they both add to 90 degrees

90 - 12.1 = 77.9

the other angle is 77.9 degrees
