Question

A ship is headed due north at a constant 22 miles per hour. Because of the ocean current, the true course of the ship is 15°.

Answer 1

I am not too sure of this but think about it.

Answer 2

Find side a using the Law of Cosines.
Find the angle b using the Law of Sines.
Subtract angle b from 90 degrees getting the angle to get the angle that side a is off from the horizontal. That angle, I believe is the direction of the current.
