The triangles shown in adjoining figures are similar. Find the values of a and b.

Explanation

To solve the problem of finding the values of \( a \) and \( b \) in the similar triangles, we can follow these steps:

### Step 1: Identify the Similar Triangles
Given that the triangles are similar, we can denote the triangles as \( \triangle ABC \) and \( \triangle PQR \). The corresponding angles are equal:
- \( \angle A = \angle R \)
- \( \angle B = \angle P \)
- \( \angle C = \angle Q \)
