Here's the word problem:

A ship is headed due north at a constant 24 miles per hour. Because of the ocean current, the true course of the ship is 15°. If the currents are a constant 22 miles per hour, in what direction are the currents running?

I know there's supposed to be two answers but I just keep getting to a point where Im not even sure what angle it is that Im looking for. Any help would be great :)
