Question Analysis

This question involves the concept of complementary angles.

 

Key Concept Explanation

Complementary angles are two angles whose sum is 90 degrees. When a right - angle is indicated (even if not explicitly marked with a square but implied by the context of two angles forming a 90 - degree relationship),  we can use this property to solve for an unknown angle.

 

Step - by - Step Solution

1. Let the missing angle be .

Since the two angles are complementary, we know that .

 

2. Solve for :

Subtract
