The length of side b is 52 because using the Pythagorean theorem we know that a² + b² = c². When we plug in the known values we would get 1521 + b² = 4225, and when we subtract 1521 from both sides we would get b = 52.

So for this we will be using the pythagorean theorem, which is
a^2+b^2=c^2

. The a and b variable stand for the legs of the triangle and c represents the hypotenuse.

So to start, replace a and c variable with 39 and 65. Your equation should look like this:
39^2+b^2=65^2
