Homework Help: algebra

Posted by ann on Wednesday, April 4, 2012 at 2:00pm.

what is x short leg for right triangle
when given long leg b is 1/2x +11
when given hypotenuse c is 2x + 1

i put (-1/2x + 11) +(2x + 1) = x and came out with 20 but that did not work out when squared A + b = C.

I estimated x/a = 8, then b = 15 and c = 17 and that works 8^2 + 15^2 = 17^2 or 64 + 225 = 289 for A^2 +b^2 = c^2
could you please show me how to do it the right way?
thanks
