To find the values of \( x \), \( y \), and \( z \), let's analyze the geometry and angles in the diagram:

1. **Angle \( x \):**
   - The sum of angles on a straight line is \( 180^\circ \).
   - The angles on the straight line adjacent to \( x \) are \( 45^\circ \) and \( 66^\circ \).
   - Therefore, \( x + 45^\circ + 66^\circ = 180^\circ \).
   - Simplifying, \( x = 180^\circ - (45^\circ + 66^\circ) \).
   - \( x = 180^\circ - 111^\circ \).
   - \( x = 69^\circ \).

2. **Angle \( y \):**
   - The sum of angles in a triangle is \( 180^\circ \).
   - The angles in the triangle adjacent to \( y \) are \( 30^\circ \) and \( 43^\circ \).
   - Therefore, \( y + 30^\circ + 43^\circ = 180^\circ \).
   - Simplifying, \( y = 180^\circ - (30^\circ + 43^\circ) \).
   - \( y = 180^\circ - 73^\circ \).
   - \( y = 107^\circ \).

3. **Angle \( z \):**
   - The sum of angles on a straight line is \( 180^\circ \).
   - The angles on the straight line adjacent to \( z \) are \( 119^\circ \) and \( y \) (which we just found to be \( 107^\circ \)).
   - Therefore, \( z + 119^\circ + 107^\circ = 180^\circ \).
   - Simplifying, \( z = 180^\circ - (119^\circ + 107^\circ) \).
   - \( z = 180^\circ - 226^\circ \).
   - \( z = -46^\circ \).

This indicates a problem: the values we have obtained don't seem to align with the typical rules of geometry. Let's revisit and verify the values of angles more carefully:

1. **Angle \( x \) (Second Attempt):**
   - Correct expression: \( x + 45^\circ + 66^\circ = 180^\circ \).
   - Simplifying: \( x = 180^\circ - 111^\circ = 69^\circ \).

2. **Angle \( y \) (Second Attempt):**
   - Correct expression: \( y + 30^\circ + 43^\circ = 180^\circ \).
   - Simplifying: \( y = 180^\circ - 73^\circ = 107^\circ \).

3. **Angle \( z \) (Correction):**
   - If angle \( y \) is part of a straight line with \( z \) and \( 119^\circ \), the equation is:
   - \( y + z = 180^\circ \).
   - Substituting \( y = 107^\circ \): \( 107^\circ + z = 180^\circ \).
   - \( z = 180^\circ - 107^\circ = 73^\circ \).

Correct values:
- \( x = 69^\circ \)
- \( y = 107^\circ \)
- \( z = 73^\circ \)
