If a triangle is right, then one leg squared plus the other leg squared equals the hypotenuse squared. First, identify the hypotenuse (easier said than done- it's the longest side, always across from the right angle.) Then set up your equation and solve for the variable. You will probably need to take a square root in your last step- use your calculator to find an appropriately rounded decimal. You can do this on the x-y coordinate plane as well by counting the squares that represent the lengths of vertical and horizontal sides.
