when i worked out this question, I got the answer as X=5.1 or X=3.1
is my answer right, if it is not right .can you pls tell me and then explain to me where i went wrong.
Thank you.

6^2=x^2+(x+2)^2
solve for x
36=x^2+x^2+4x+4
2x^2+4x32=0
x^2+2x16=0
x= (2+sqrt(4+64))/2=1+sqrt17
x=1+4.17
then, since it makes no sense for x to be negative, the x=3.17, and the last side then is 5.17
