Answer :
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
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
