So, we know that a^2 + b^2 = c^2.  Right?  That is called the Pythagorean Theorem.
In this case.  We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b.  a & b are just the two legs of the right triangle.
So, if we say that 39 is a, 40 is b, and x is c.  We can plug it into the Pythagorean Theorem.
39^2 + 40^2 = x^2
I'll let you take it from there.
