1. **State the problem:** We need to find the bearing of point C from point B. 2. **Understanding bearings:** Bearings are measured clockwise from the north direction. 3. **Given information:** - At point B, the angle between north and line CB is 20°. - This means the bearing of C from B is measured clockwise from north at B. 4. **Calculate the bearing:** Since the angle between north and CB at B is 20°, the bearing of C from B is simply 20°. 5. **Final answer:** The bearing of C from B is **20°**.
