Question

the measure of an angle is 45.1°. 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 $\theta = 45.1^{\circ}$. The complementary angle $\alpha=90^{\circ}-\theta$. So, $\alpha = 90 - 45.1=44.9^{\circ}$.

Answer:

$44.9^{\circ}$
