In this diagram, we have two intersecting lines, creating several pairs of angles. Let's solve for the missing angles based on the given values and the properties of vertical and supplementary angles.

### Known Angles:
- \( h = 123^\circ \)
- \( m = 81^\circ \)

### Steps:

1. **Find \( g \):**
   - Angle \( g \) is vertically opposite to \( h \). Vertically opposite angles are equal, so:
   \[
   g = h = 123^\circ
   \]

2. **Find \( k \):**
   - Angle \( k \) is vertically opposite to \( m \). Similarly, vertically opposite angles are equal, so:
   \[
   k = m = 81^\circ
   \]

3. **Verify the relationships:**
   - Angles \( h \) and \( m \) are supplementary because they are adjacent and form a straight line. The sum of supplementary angles is \( 180^\circ \):
   \[
   h + m = 123^\circ + 81^\circ = 204^\circ
   \]
   This confirms that both angles are on a straight line, and the other pairs follow the same relationships.

### Final Answer:
- \( g = 123^\circ \)
- \( h = 123^\circ \)
- \( k = 81^\circ \)
- \( m = 81^\circ \)
