To find the horizontal (\( F_H \)) and vertical (\( F_V \)) components of the forces, we use trigonometry. The general formulas are:

- \( F_H = F \cos(\theta) \)
- \( F_V = F \sin(\theta) \)

Where:
- \( F \) is the magnitude of the force,
- \( \theta \) is the angle the force makes with the horizontal axis.

### For the first force (12 N at 35°):
- Horizontal component:  
  \( F_H = 12 \cos(35^\circ) \)
  \( F_H \approx 12 \times 0.8192 \approx 9.8 \, \text{N} \)
  
- Vertical component:  
  \( F_V = 12 \sin(35^\circ) \)
  \( F_V \approx 12 \times 0.5736 \approx 6.9 \, \text{N} \)

### For the second force (7 N at 73°):
- Horizontal component:  
  \( F_H = 7 \cos(73^\circ) \)
  \( F_H \approx 7 \times 0.2924 \approx 2.0 \, \text{N} \)
  
- Vertical component:  
  \( F_V = 7 \sin(73^\circ) \)
  \( F_V \approx 7 \times 0.9563 \approx 6.7 \, \text{N} \)

### Final Answers:
1. For the 12 N force:
   - \( F_H \approx 9.8 \, \text{N} \)
   - \( F_V \approx 6.9 \, \text{N} \)

2. For the 7 N force:
   - \( F_H \approx 2.0 \, \text{N} \)
   - \( F_V \approx 6.7 \, \text{N} \)
