Question 744517: A skateboarder is building a ramp. If the ramp is 12.5 feet tall and 15 feet long how long is the base of the ramp?
Answer by Cromlix(4381) (Show Source): You can put this solution on YOUR website!
This a Pythagorean problem.
The hypotenuse = 15 ft long
One of the sides = 12.5 feet
The base of the ramp represents the remaining side.
Base ^2 + side ^2 = hypotenuse ^2
Base ^2 = hypotenuse ^2 - side ^2
Base ^2 = 15 ^2 - 12.5 ^2
Base ^2 = 68.75
Base = square root of 68.75
Base = 8.3 ft
