Question

the measure of an angle is 53°. what is the measure of its complementary angle?

Explanation:

Step1: Definición de ángulos complementarios

Los ángulos complementarios suman 90°.

Step2: Cálculo del ángulo complementario

Sean $\alpha = 53^{\circ}$ y $\beta$ el ángulo complementario. Entonces $\beta=90^{\circ}-\alpha$. Sustituyendo $\alpha = 53^{\circ}$, tenemos $\beta = 90^{\circ}- 53^{\circ}=37^{\circ}$.

Answer:

$37^{\circ}$
