**Problem 3: Understanding Similar Polygons**

The task is to find the value of each variable given that the polygons are similar.

**Diagram A:**

This part of the diagram displays two triangles. The left triangle has:

- A side labeled as \( y \)
- The other sides are labeled as 4 and 12.

The right triangle has:

- Corresponding side labeled as 12
- The other sides are labeled as 6 and 18.

The variables \( x \) and \( y \) correspond to angles in each triangle.

**Diagram B:**

This section shows two intersecting triangles with a common middle segment. The left triangle features:

- Side \( b \) opposite angle labeled with a curve
- Other side measures as 9.

The right triangle includes:

- Side \( a \) opposite angle labeled with a curve
- Other sides measure 15 and 10.

The triangles share a base of 12.

**Instruction:**

Using the principle that corresponding angles are equal and corresponding sides are proportional in similar polygons, solve for each variable.
