I have so far

let one leg be x

the other leg will be x-10

x^2 +(x-10)^2=22^2

x^2+x^2-20x+100=484

x^2+x^2-20x+100=484

2x^2 - 20x - 384 = 0

x^2 - 10x - 192 = 0

I used the formula to solve for x

x = 19.7309

one side is 19.7309, the other 9.7309

--> 2x^2-20x-384=0

--> x^2-10x-192=0

Now apply quadratic formula.
