## anonymous 5 years ago Find the length of the hypotenuse for a right triangle with legs of 5 and 12 units.

Pythagorean theorem states where c is the hypotenuse (longest side) is:$c ^{2}=a ^{2}+b ^{2}$

$c ^{2}=25+144=169$ $c ^{2}=169$ $c=\sqrt{169}=13$

So, I got a huge number when I did it?..

Oh, wait, nm, I just cubed it. Wow.

It doesn't say what the units were so it is just 13 (units)

Did you follow what did with understanding?

I don't really understand where the 25 and the 144 come from?

I should of shown that the 25 is 5 squared the 144 is 12 squared like the theorem shows a squared and b squared
