Problema Solution
The angle that a waterskiing ramp forms with the surface of water is 15 degrees, and the ramp rises 5 feet. Approximately how long is the ramp?
Answer provided by our tutors
the ramp length is 58.14 feet
Solution: the angle between the ramp and surface is 15degree, the height of the vertical part is 5Feet
so set the ramp is A, use the trigonometric function sin15o = 15/A = 0.2588
then A = 58.14 feet
