Question

the measure of an angle is 81.5°. 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

Sean $\alpha = 81.5^{\circ}$ y $\beta$ el ángulo complementario. Entonces $\beta=90^{\circ}-\alpha$. Sustituyendo $\alpha = 81.5^{\circ}$, tenemos $\beta = 90^{\circ}-81.5^{\circ}=8.5^{\circ}$.

Answer:

$8.5$
