Answer:
Explanation:
The Pythagorean theorem says:

where a and b are the two legs of the triangle and c is the hypotenuse. Here, let's say a = 6 and b =
. We then get the following equation:

So c = 7. Technically, c can also equal -7 since (-7)^2 = 49 as well but that does not apply here because a side length cannot be <0. So 7 is the answer.
