Question

find the measure of the missing angle.

Explanation:

Step1: Recall angle - sum property

The two angles shown are complementary, meaning their sum is 90°. Let the missing angle be $\alpha$. We know that $\alpha+57^{\circ}=90^{\circ}$.

Step2: Solve for the missing angle

$\alpha = 90^{\circ}-57^{\circ}$.

Answer:

$33^{\circ}$
