Question

find the measure of the missing angle.

Explanation:

Step1: Recall angle - sum property

The two angles are complementary, and their sum is 90°. Let the missing angle be \(a\). So, \(a + 54^{\circ}=90^{\circ}\).

Step2: Solve for \(a\)

Subtract 54° from both sides of the equation: \(a=90^{\circ}- 54^{\circ}\).

Answer:

\(36^{\circ}\)
