Question

the measure of an angle is 41°. what is the measure of its supplementary angle?

Explanation:

Step1: Recall supplement - angle definition

Supplementary angles add up to 180°.

Step2: Set up the subtraction

Let the given angle be \(a = 41^{\circ}\), and the supplementary angle be \(x\). Then \(x=180 - a\).

Step3: Calculate the supplementary - angle measure

\(x = 180^{\circ}-41^{\circ}=139^{\circ}\)

Answer:

\(139^{\circ}\)
