1. **Problem statement:** We have an equilateral triangle formed by towns L, M, and N. The bearing of M from L is 103°. We need to find the bearing of L from N. 2. **Understanding bearings:** Bearings are measured clockwise from the north direction. An equilateral triangle has all sides equal and all internal angles equal to 60°. 3. **Given:** Bearing of M from L is 103°. This means if you stand at L facing north, you turn 103° clockwise to face M. 4. **Step to find bearing of L from N:** Since the triangle is equilateral, all sides and angles are equal. 5. **Visualizing the triangle:** - L to M bearing is 103°. - The angle at each vertex is 60°. 6. **Calculate bearing of N from L:** Since the triangle is equilateral, the bearing from L to N is 103° - 60° = 43°. 7. **Calculate bearing of L from N:** The bearing from N to L is the bearing from L to N plus 180° (because bearings are directional and opposite directions differ by 180°). So, bearing of L from N = 43° + 180° = 223°. 8. **Final answer:** The bearing of L from N is **223°**.
