Question 876329: This question is pythagorean theorem (i think) but it has algebra in it and I'm not sure how to do it.
I have to find the length of each side when leg a= (x-1), leg b= 6cm and the hypotenuse= (x+1)
Just was wondering if you knew how to do it, because I've got an exam in it tomorrow :?
Thanks

Hi

Applying the Pythagorean Theorem

(x-1)^2 + 6^2 = (x+1)^2

x^2 - 2x + 1 + 36 = x^2 + 2x + 1

            36 = 4x

             9 = x

Other Leg = 8cm and Hyp = 10cm

CHECKING our answer***

 64cm^2 + 36cm^2 = 100cm^2

Wish You the Best in your Studies.
