Question

find the measure of the missing angle.

Explanation:

Step1: Identify the relationship between angles

The two angles \(a\) and \(54^{\circ}\) are complementary (they form a right - angle, so their sum is \(90^{\circ}\)).

Step2: Set up the equation

\(a + 54^{\circ}=90^{\circ}\)

Step3: Solve for \(a\)

\(a=90^{\circ}- 54^{\circ}\)
\(a = 36^{\circ}\)

Answer:

\(36^{\circ}\)
