You can put this solution on YOUR website! you are building a skateboars ramp with a piece of plywood that is 8 feet long. you want the height of the ramp to be 5 feet. to make a strong ramp the base must forma right angle with the back of the ramp. what will be the length of the base rounded to the nearest tenth of a foot?
-------------------
Since the right angle is at the top of the ramp, the hypotenuse will be on the ground, so 8 and 5 are the sides.
Use Pythagoras:
h^2 = 8^2 + 5^2
h^2 = 64 + 25 = 89
h = sqrt(89)
h = 9.4 feet
