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

### Given Information:
- The diagram shows two intersecting lines and multiple transversal lines.
- Three angles are provided: 
  - \( 44^\circ \)
  - \( 78^\circ \)
  - \( 66^\circ \)
  
We can use properties of parallel lines and angles formed by transversals (corresponding angles, alternate interior angles, vertical angles, and supplementary angles) to solve for the missing angles \(a\), \(b\), \(c\), \(d\), \(e\), and \(f\).

### Step-by-step Solution:

1. **Angle \( a \)**:
   - Angle \( a \) is supplementary to the angle labeled \( 44^\circ \) (linear pair). Therefore,
     \[
     a = 180^\circ - 44^\circ = 136^\circ.
     \]

2. **Angle \( b \)**:
   - Angle \( b \) is vertically opposite to \( 66^\circ \), and vertically opposite angles are equal. Therefore,
     \[
     b = 66^\circ.
     \]

3. **Angle \( c \)**:
   - Angle \( c \) is corresponding to \( 44^\circ \) (because of the parallel lines and transversal). Therefore,
     \[
     c = 44^\circ.
     \]

4. **Angle \( d \)**:
   - Angle \( d \) is vertically opposite to \( 78^\circ \). Therefore,
     \[
     d = 78^\circ.
     \]

5. **Angle \( e \)**:
   - Angle \( e \) is supplementary to \( 66^\circ \) (linear pair). Therefore,
     \[
     e = 180^\circ - 66^\circ = 114^\circ.
     \]

6. **Angle \( f \)**:
   - Angle \( f \) is vertically opposite to angle \( e \), and thus, it is equal to \( e \). Therefore,
     \[
     f = 114^\circ.
     \]

### Final Answer:
- \( a = 136^\circ \)
- \( b = 66^\circ \)
- \( c = 44^\circ \)
- \( d = 78^\circ \)
- \( e = 114^\circ \)
- \( f = 114^\circ \)
