Question

find the measure of the missing angle.

Explanation:

Step1: Identify angle relationship

The two angles (124° and the missing angle) are supplementary (they form a linear pair), so their sum is 180°.

Step2: Calculate missing angle

Let \( x \) be the missing angle. Then \( x + 124^\circ = 180^\circ \). Solving for \( x \), we get \( x = 180^\circ - 124^\circ \).
\( x = 56^\circ \)

Answer:

\( 56^\circ \)
