Question

the measure of an angle is 27°. what is the measure of its supplementary angle?

Explanation:

Step1: Recall supplementary - angle definition

Supplementary angles add up to 180°.

Step2: Calculate the supplementary angle

Let the given angle be \(a = 27^{\circ}\), and the supplementary angle be \(x\). Then \(x=180 - a\). Substitute \(a = 27^{\circ}\) into the formula: \(x = 180-27=153^{\circ}\).

Answer:

153
