2 radar stations A & B \re 80 km apart and B is due east of A. one aircraft is on a bearing 30 from A and 346 from B. A second aircraft is on a bearing of 325 from A and 293 from B. how far apart are the two aircrafts?

Sketch attached ... bearings are measured in degrees clockwise from North. First aircraft is at C; second is at D.

Figure out the angles from the given bearing information and use the known length of AB to determine CD.

Using the law of sines is a good start.
