From the image, we see that angle \( \angle 1 = 125^\circ \) is provided. The task is to find the values of \( \angle 2 \), \( \angle 3 \), and \( \angle 4 \).

The figure shows lines \( a \) and \( b \) intersecting at a point, and angles are labeled around the intersection point.

### Key geometric principles:
1. **Linear pair**: Angles on a straight line sum to \( 180^\circ \).
2. **Vertical angles**: Opposite angles formed by two intersecting lines are equal.

### Step-by-step solution:
- \( \angle 1 \) and \( \angle 2 \) form a linear pair, so:
  \[
  \angle 1 + \angle 2 = 180^\circ
  \]
  Substituting \( \angle 1 = 125^\circ \):
  \[
  125^\circ + \angle 2 = 180^\circ
  \]
  \[
  \angle 2 = 180^\circ - 125^\circ = 55^\circ
  \]

- \( \angle 2 \) and \( \angle 4 \) are
