I found 3and5

Explanation:

We can use Pythagoras theorem where a and b are the two sides and c=34 is the hipotenuse to get:
c2=a2+b2
you also know that a+b=8
or a=8b into c2=a2+b2 you get:
34=(8b)2+b2
34=6416b+b2+b2
2b216b+30=0
Using the Quadratic Formula:
b1,2=16±2562404=16±44
getting:
b1=5
b2=3
and:
a1=85=3
a2=83=5
