Kobe, Carter, Emory, Jackson, Josh, and Cameron are all out playing golf. Carter smashes a drive with an angle of elevation of 15 degrees. If the highest point of the drive was at 60 feet, how far was the ball when it was at 60 feet in the air? (Yes I am fully aware this won't generate a true right triangle. Draw it as though it were one.)
