On a map, Town A is 8 km due south of Town B, Town C is 9 km from Town A, and Town C is 3 km from Town B (see figure below). Find the bearing from Town A to Town C and the bearing from Town B to Town C.

Hello, there is no figure but I shall try my best to figure it out.
I think this is probably a triangle.
B
 C

A
AB= 8
AC=9
BC=3
A is 9 km SW of C and B is 3 km NW of C. I hope this helps.

No problem!

To find the actual bearings, find the angles A,B,C, using the law of cosines. For example,
BC^{2} = AB^{2} + AC^{2}  2*AB*AC*cosA
9 = 64 + 81  144cosA
cosA = 136/144
A = 19º
