Question

find the measure of the missing angle.

Explanation:

Step1: Identify angle - type relationship

The two angles are complementary (sum to 90° as indicated by the right - angle symbol).

Step2: Set up the equation

Let the missing angle be \(a\). We know that \(a + 29^{\circ}=90^{\circ}\).

Step3: Solve for \(a\)

\(a=90^{\circ}- 29^{\circ}\).
\(a = 61^{\circ}\)

Answer:

\(61^{\circ}\)
