**Solve for x and y in each triangle:**

1. **Triangle 13:**
   - Isosceles triangle with two equal angles and one unique angle.
   - One angle measures \(82^\circ\).
   - The equations for the sides are \(2x-11\) and \(7y\).

2. **Triangle 14:**
   - Isosceles triangle with two equal sides.
   - The angle opposite the equal sides is labeled as \(y^\circ\).
   - The equations for the sides are \(9x+1\) and \(2x+5\).

3. **Triangle 15:**
   - Generic triangle with sides and one known angle.
   - One angle measures \(48^\circ\).
   - The equations for the sides are \(3y-2\), \(3x+6\), and a side length of 22.

4. **Triangle 16:**
   - Isosceles triangle with two equal sides.
   - One angle measures \(42^\circ\).
   - The equations for the sides are \(4y-11\) and \(x\).

Students need to use geometric principles and algebra to find the values of \(x\) and \(y\) for each triangle based on the provided equations and measurements.
