Using bearings to solve triangles

For trigonometry, I have a problem that states the following.

A ship travels 93km on a bearing of 14 degrees, and then travels on a bearing of 104 degrees for 139 km. Find the distance of the end of the trip from the starting point, to the nearest kilometer.

Don't really know how to begin with this one, as I don't even know how to work out a problem regarding "bearings".

My answer key says it equals 167.

The angle between the two legs of the journey is 90 degrees. Use the Pythagorean theorem for right-angled triangles.
