Question

1. find the measure of this angle. type a response 1 of 7 next →

Explanation:

Step1: Use the property of supplementary angles

Supplementary angles add up to \(180^{\circ}\). Let the measure of angle \(1\) be \(x\). Then \(x + 72^{\circ}=180^{\circ}\).

Step2: Solve for \(x\)

Subtract \(72^{\circ}\) from both sides: \(x=180^{\circ}- 72^{\circ}\).

Answer:

\(108^{\circ}\)
