Problem
(1) In the figure below, \( \triangle A B C \sim \triangle X Y Z \). What is the \( m \angle A \) ? (A) \( m \angle A=85^{\circ} \) (B) \( m \angle A=35^{\circ} \) (C) \( m \angle A=60^{\circ} \) (D) \( m \angle A=120^{\circ} \)
Solution
Step 1 ：\( \triangle A B C \sim \triangle X Y Z \)
Step 2 ：\( m \angle A = m \angle X \)
Step 3 ：\( m \angle A=85^{\circ} \)
