Question 857593
Call the sides as x, y, and h.  Use h for hypotenuse.


Description gives {{{h=x+10}}} and {{{h=y+80}}}.  Another relationship is {{{h^2=x^2+y^2}}}, since this triangle is a Right Triangle.


Can you find a simple plan to solve for x, y, and h?  Tell me if you can or cannot finish; especially if you cannot.
