Question

these angles are supplementary. what is the measure of ∠x? x = ?°

Explanation:

Step1: Recall supplementary - angle property

Supplementary angles add up to 180°.

Step2: Set up an equation

Let the measure of ∠x be \(x\). Then \(x + 63^{\circ}=180^{\circ}\).

Step3: Solve for \(x\)

\(x=180^{\circ}- 63^{\circ}\).

Answer:

117°
