Question

find the measure of the missing angle.
60°
a
a =

Explanation:

Step1: Identify the angle type

The angle is a right angle, so the sum of the two acute angles is \( 90^\circ \).

Step2: Calculate the missing angle

We know one angle is \( 60^\circ \), so the missing angle \( a = 90^\circ - 60^\circ \).
\( a = 30^\circ \)

Answer:

\( 30^\circ \)
