Sailor · Answer

You know the formula for Pythagorean theorem right?

dukedadon · Answer

yes.

Sailor · Answer

Ok. So the hypotenuse is always C. For the legs of the triangle, It wouldn't matter the order as long as the equation is set up right. So you should get an equation of $$5^{2}+x ^{2}=8^{2}$$
