Question

the measure of an angle is 66.2°. what is the measure of its complementary angle?

Explanation:

Step1: Recall complementary - angle definition

Complementary angles add up to 90°.

Step2: Calculate the complementary angle

Let the given angle be $\alpha = 66.2^{\circ}$, and the complementary angle be $\beta$. Then $\beta=90^{\circ}-\alpha$. So, $\beta = 90 - 66.2=23.8^{\circ}$.

Answer:

$23.8$
