1. Two towers A and B are 18.5 miles apart. The bearing from A to B is N65E. A fire is spotted by ranger at both towers. Its bearing from A and B are N28e and N16.5W. This makes a triangle with A and B and C the fire. Can anyone give me a clue and finding angles A and B? 2. a/sin A = b/sin B 3. I found angle B was 138.5, except it wasn't right.
