As long as you have 2 sides of a right triangle, you can use Pythagoras to find the third side. You can just solve for the square of the side you want to find.
leg%5B1%5D%5E2%2Bleg%5B2%5D%5E2=hypotenuse%5E2 --> leg%5B2%5D%5E2=hypotenuse%5E2-leg%5B1%5D%5E2

EXAMPLE:
hypotenuse = 5feet, known leg = 3feet, other leg = x feet
Pythagoras says:
x%5E2%2B3%5E2=5%5E2
x%5E2%2B9=25
x%5E2=25-9
x%5E2=16
x=4
