Question

the measure of an angle is 97.3°. what is the measure of its supplementary angle?

Explanation:

Step1: Recall supplementary - angle concept

Supplementary angles add up to 180°.

Step2: Calculate the supplementary angle

Let the given angle be $\alpha = 97.3^{\circ}$, and the supplementary angle be $\beta$. Then $\beta=180^{\circ}-\alpha$.
So, $\beta = 180 - 97.3=82.7^{\circ}$

Answer:

$82.7$
