Question

a supplement of an angle is twice as large as the angle. find the measure of the angle. after you enter your answer press go.

Explanation:

Step1: Set up the equation

Let the angle be \(x\). Its supplement is \(180 - x\). Given \(180 - x=2x\).

Step2: Solve the equation

Add \(x\) to both sides: \(180 = 2x+x\), so \(180 = 3x\). Then divide both sides by \(3\): \(x=\frac{180}{3}\).

Answer:

\(60\)
