Question

the measure of an angle is 16°. 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 measure

Let the given angle be $\theta = 16^{\circ}$. The measure of its complementary angle $\alpha$ is $\alpha=90^{\circ}-\theta$.
So, $\alpha = 90^{\circ}-16^{\circ}=74^{\circ}$.

Answer:

$74^{\circ}$
