Two ocean liners leave from the same port in Puerto Rico at 10:00 a.m. One travels at a bearing of N 46 degrees W at 12 miles per hour, and the other travels at a bearing of S 55 degrees W at 14 miles per hour. Approximate the distance between them at noon the same day. This is the problem.
When I solved this problem I used the law of cosines and used cos 101 degrees but I guess I was suppose to use cos 79 degrees. I don't understand why. Can you explain it to me?
