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°. So we have the equation \(a + 126^{\circ}=180^{\circ}\).

Step2: Solve for \(a\)

Subtract 126° from both sides of the equation: \(a=180^{\circ}- 126^{\circ}\).

Answer:

\(54^{\circ}\)
