Let's analyze the given diagram to find the missing angles.

### Key observations:
1. The angle given between the two diagonal lines is \( 51^\circ \).
2. There is a right angle \( d \) at the bottom formed by two perpendicular lines.
3. The lines intersect, forming a vertical angle relationship, which means angles directly opposite to each other are congruent.

### Steps to find the missing angles:

1. **Angle \( e \):** 
   - \( e \) and \( 51^\circ \) form a linear pair, meaning they are supplementary (sum to \( 180^\circ \)).
   - So, \( e = 180^\circ - 51^\circ = 129^\circ \).

2. **Angle \( f \):** 
   - Angle \( f \) is vertically opposite to \( 51^\circ \), so it is also \( 51^\circ \) (since vertical angles are congruent).

3. **Angle \( d \):** 
   - \( d \) is a right angle, already marked as \( 90^\circ \), so no further calculation is needed.

### Final values:
- Angle \( e = 129^\circ \)
- Angle \( f = 51^\circ \)
- Angle \( d = 90^\circ \)
