Question 982019
Right triangle with sides x, y, x+8.  The shorter side is x.  Hypotenuse x+8 is also the diagonal from the rectangle.  x and y are the dimensions of the rectangle.


{{{xy=60}}}, the rectangle.


{{{x^2+y^2=(x+8)^2}}}, for the triangle.  Neat things happen when you simplify this equation.
