1. **Geometry Problem:**
- **Angle \( A \) = 20°**
- **Side \( a \) = 15**
- **Side \( b \) = 22**
2. **Vector Problem:**
- Write vector \( \vec{v} = \overrightarrow{AB} \) in component form where:
- **Point \( A = (6, 8) \)**
- **Point \( B = (5, 7) \)**
### Explanation:
#### Vector Components:
To write the vector \( \overrightarrow{AB} \) in component form, subtract the coordinates of point \( A \) from point \( B \).
- **\( \overrightarrow{AB} = (x_2 - x_1, y_2 - y_1) \)**
- **\( \overrightarrow{AB} = (5 - 6, 7 - 8) \)**
- **\( \overrightarrow{AB} = (-1, -1) \)**
This vector \( \overrightarrow{AB} \) is represented by the components \( (-1, -1) \), indicating the direction and magnitude from point \( A \) to point \( B \).
