I can't figure this out.

A famous golfer tees off on a long, straight 459 yard par 4 and slices his drive 10 degrees to the right of the line from tee to the hole. If the drive went 288 yards, how many yards will the golfer's second shot have to be to reach the hole?

1 answer

just use the law of cosines:

x^2 = 459^2 + 288^2 - 2*459*288 cos 10°
