1. I think the reason I can't figure this problem out is because I'm not quite sure how to draw the picture.

"A boat race runs along a triangular course marked by buoys A, B, and C. The race starts with the boats headed west for 2500 meters. The other two sides of the course lie to the north of the first side, and their lengths are 1100 meters and 2000 meters. Draw a diagram to represent the problem and find the bearings for the last two legs of the race."

I too would use the cos rule for this question, but A is not the bearing of mineapolis from phoenix. Look at the diagram, and try again2. "On a map, Minneapolis is 165 millimeters due west of Albany, Phoenix is 216 millimeters from Minneapolis, and Phoenix is 368 millimeters from Albany.

a). Find the bearing of Minneapolis from Phoenix."

Here's what I did:

cosA= (360^2+216^2-165^2)/(2(368)(216))

A= cos^-1(154,855/158,976)

A=13.1 degrees

Therefore, the bearing is N13.1W.

3. Once again, I think I am just drawing the picture incorrectly.

"On a baseball diamond with 90-foot sides, the pitcher's mound is 60.5 feet from home plate. How far is it from the pitcher's mound to third base?"
