A wheelchair ramp is to be built from the ground to the door sill along side a building. The cross section of the ramp is a right triangle with a base that is 12 inches more than the three times the height of the door sill from the ground and a hypotenuse that is 35 inches more than twice the height. Use the Pythagorean theorem to write a quadratic equation. (Find the height base and hypotenuse of the ramp. (Round off to the nearest 100th of an inch.

    If the base is 12 inches more than 3 times the height, you can start to set up your equation.

    b=3h+12

    If the hypotenuse is 35 inches more than twice the height, you have another equation.

    H=2h+35

    h^2+b^2=H^2

    (2h+35) ^2 - (3h+12) ^2 = h^2
