For some reason I am having a terrible time with some bearing problems that were assigned. Any help would be greatly appreciated.

1. An airplane flew 450mi at a bearing of N65*E from Airport A to Airport B. The plane then flew at a bearing of S38*E to airport C. Find the distance from A to C if the bearing from airport A to Airport C is S60*E *=degrees

I can't get my angles to work out I know to use the law of sines, but I'm getting the wrong angles?

2. The Sides of a parallelogram are 10 feet and 14 feet. The longer diagonal is 18 feet. Find the length of the shorter diagonal of the parallelogram.

I don't understand how the shorter diagonal would look? |\| but wouldn't the shorter diagonal just make it look like an x inside of a box?

3. The heading and air speed of an airplane are 60* and 250 mph, respectively. If the wind is 50 mph with a direction of 150*, find the ground speed and resulting course (direction) of the plane.

I have no idea where to start this problem?
