What side length can make a triangle with side lengths 8 and 12?

This would require use of the Pythagorean Theorem. If you don't know what this is, it's a formula for determining side lengths of triangles. The longest side is the hypotenuse. The other 2 are called the legs. What you do is: you square the side lengths. This means you multiply the length by itself. then you have to make sure the hypotenuse squared is larger than both legs squared.

Iam pretty sure its a sorry if im wrong

(-8,5) bu tun not sure ok
