Question

these figures are congruent. what is m∠b?

Explanation:

Step1: Recall congruent - figure property

Corresponding angles of congruent figures are equal.

Step2: Identify corresponding angle

\(\angle B\) corresponds to \(\angle L\) in the congruent figures.

Step3: Find the measure of \(\angle B\)

Since \(m\angle L = 130^{\circ}\), then \(m\angle B=130^{\circ}\).

Answer:

\(130^{\circ}\)
