The measure of an angle is 27°. What is the measure of its complementary angle?

The measure of a complementary angle can be found by subtracting the given angle from 90 degrees. Therefore, the measure of the complementary angle is 90° - 27° = <<90-27=63>>63°.

To find the measure of the complementary angle, we need to know that complementary angles are two angles that add up to 90 degrees. Given that the measure of the given angle is 27°, we can find its complementary angle by subtracting the given angle from 90°.

Complementary angle = 90° - Given angle

Complementary angle = 90° - 27°

Complementary angle = 63°

Therefore, the measure of the complementary angle is 63 degrees.
