Question

the measure of an angle is 88.7°. what is the measure of its supplementary an

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 \(x + 88.7^{\circ}=180^{\circ}\), so \(x = 180^{\circ}- 88.7^{\circ}\).

$$x=91.3^{\circ}$$

Answer:

\(91.3\)
