Question Analysis

This question involves the concept of supplementary angles.

 

Key Concept Explanation

Supplementary angles are two angles whose sum is 180°. When two angles form a straight line (a linear pair), they are supplementary.

 

Step-by-Step Solution

1. Let the measure of the missing angle be .

2. We know that one angle is 132°.

3. Since the two angles form a linear pair, we can set up the equation .

4. To solve for , we subtract 132° from both sides of the equation: .
