Question

1. find the indicated value.

a. find the measure of ∠b.

Explanation:

Step1: Identify right angle

The diagram has a right angle (90°) composed of ∠b and 62°.

Step2: Calculate ∠b

Use the formula for complementary angles: \( \angle b + 62^\circ = 90^\circ \). Solve for \( \angle b \): \( \angle b = 90^\circ - 62^\circ = 28^\circ \).

Answer:

\( 28^\circ \)
