Problem

A pilot is flying at 168 mph. She wants her flight path to be on a bearing of 57 degrees and 40 minutes. A wind is blowing from the South at 27.1 mph. Find the bearing the pilot should fly, and find the plane's ground speed.

Hint:

Can you use the Law of Cosines to solve for x?

Then, use Law of Sines to solve for the angle at A.



 

The angle at B is 57 degrees and 40 minutes.
