Question

find ( mangle r ).
( \triangle abc ) is congruent to ( \triangle rqp ).

Explanation:

Step1: Use congruent triangle property

Since \(\triangle ABC\cong\triangle RQP\), corresponding angles are equal. \(\angle A\) corresponds to \(\angle R\).

Step2: Identify \(\angle A\)

From \(\triangle ABC\), \(\angle A = 75^{\circ}\).

Answer:

\(m\angle R = 75^{\circ}\)
