The diagram depicts two intersecting lines, forming several angles. Based on the image, angle measures \( a \), \( b \), and \( c \) are to be found, where \( 53^\circ \) is given.

### Key concepts to use:
- **Vertically opposite angles** are equal.
- **Adjacent angles** formed on a straight line sum to \( 180^\circ \).

### Step-by-step solution:
1. **Angle \( a \):**
   - \( a \) and \( 53^\circ \) are vertically opposite angles.
   - Vertically opposite angles are equal, so \( a = 53^\circ \).

2. **Angle \( b \):**
   - \( b \) and \( 53^\circ \) form a linear pair (they lie on a straight line).
   - The sum of angles on a straight line is \( 180^\circ \).
   - So, \( b + 53^\circ = 180^\circ \).
   - Solving for \( b \): 
   \[
   b = 180^\circ - 53^\circ = 127^\circ.
   \]

3. **Angle \( c \):**
   - \( c \) and \( b \) are vertically opposite angles.
   - Therefore, \( c = b = 127^\circ \).

### Final values:
- \( a = 53^\circ \)
- \( b = 127^\circ \)
- \( c = 127^\circ \)
