The diagram shows two parallel lines \( m \parallel n \) cut by a transversal. We are asked to find the values of \( x^\circ \) and \( y^\circ \).

### Step-by-step solution:

1. **Angle \( y^\circ \)**:
   - The given angle of \( 116^\circ \) is vertically opposite to \( y^\circ \) since they are on opposite sides of the transversal.
   - **Vertically opposite angles are equal**, so:
     \[
     y = 116^\circ
     \]

2. **Angle \( x^\circ \)**:
   - The angles \( x^\circ \) and \( 116^\circ \) are on the same side of the transversal and form a **co-interior angle** pair between the parallel lines \( m \) and \( n \).
   - For co-interior angles, the sum of the angles is \( 180^\circ \):
     \[
     x + 116^\circ = 180^\circ
     \]
   - Solving for \( x \):
     \[
     x = 180^\circ - 116^\circ = 64^\circ
     \]

### Final values:
- \( x = 64^\circ \)
- \( y = 116^\circ \)
