The measure of an angle is 49.2°. What is the measure of its complementary angle?

40.8°

Explanation:

Given that,

The measure of an angle is 49.2°.

We need to find the measure of its complementary angle. We know that for a complementary angle, the sum of two angles is equal to 90 degrees. So,

a+b = 90

49.2+b = 90

b = 90-49.2

b = 40.8°

So, the measure of its complementary angle is 40.8°.
