Question

the measure of an angle is 167°. what is the measure of its supplementary angle?

Explanation:

Step1: Recall supplementary angle definition

Supplementary angles sum to \(180^\circ\). Let the supplementary angle be \(x\).

Step2: Set up equation and solve

\(167^\circ + x = 180^\circ\), so \(x = 180^\circ - 167^\circ\).
\(x = 13^\circ\)

Answer:

\(13^\circ\)
