question
find the measure of the missing angle.

Explanation:

Step1: Identify angle relationship

The two angles (106° and \( a \)) are supplementary (form a straight line, sum to 180°).

Step2: Calculate missing angle

Use the formula \( a = 180^\circ - 106^\circ \).
\( a = 74^\circ \)

Answer:

\( 74^\circ \)
