Question

the measure of an angle is 41.9°. what is the measure of its supplementary angle?

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles add up to \(180^{\circ}\).

Step2: Calculate the supplementary angle

Let the supplementary angle be \(x\). Then \(x + 41.9^{\circ}=180^{\circ}\), so \(x = 180^{\circ}- 41.9^{\circ}\).

$$x=180 - 41.9=138.1$$

Answer:

\(138.1\)
