Question

find the measure of the missing angle.
answer attempt 1 out of 2
a =

Explanation:

Step1: Recall angle - sum property

The two angles are supplementary, meaning their sum is 180°. Let the missing angle be \(a\) and the given angle be 63°. So, \(a + 63^{\circ}=180^{\circ}\).

Step2: Solve for \(a\)

Subtract 63° from both sides of the equation: \(a=180^{\circ}- 63^{\circ}\).
