Question

the measure of an angle is 13°. what is the measure of its complementary angle?

Explanation:

Step1: Record la definición de ángulos complementarios

Dos ángulos son complementarios si la suma de sus medidas es 90°.

Step2: Calcular el ángulo complementario

Sea $x$ el ángulo complementario. Entonces $x + 13^{\circ}=90^{\circ}$, así que $x = 90^{\circ}- 13^{\circ}$.
$x=77^{\circ}$

Answer:

$77$
