Hello!

The pythagorean theorem states that a%5E2%2Bb%5E2=c%5E2, with c being the hypotenuse and a being 12 you can easily find the value of b using the pythagorean theorem. If we subtitute we will get something like this 12%5E2%2Bb%5E2=13%5E2. In other words 144%2Bb%5E2=169, if we subtract 144 from both sides we will get b%5E2=25. To simplify these terms we need to get their respective square roots so sqrt%28b%5E2%29=sqrt%2825%29 or b=5. So the length of the other side is 5.


I hope I helped you!
