I really need help with this. The homework question reads:

A surveyor wants to find the distance across a swamp. The bearing from A to B is N32degreesW. The surveyor walks 50 meters from A and at the point C the bearing to B is N68degreesW. Find (a) the bearing from A to C and (b) the distance from A to B.

I already got the answer for (a) that was easy. But how do I get (b)? I'm confused!!
