Im guessing 21 and 72 are the side lengths for the triangle?
Alright, so since it's a right triangle you can use the Pythagorean theorem or a^2+b^2=c^2
Since i cant see the picture, im going to use some general math <span>so i</span> can figure out if those two sides are the legs or if one of them is the hypotenuse Alright so im guessing the side we're trying to find is the hypotenuse
You can theoretically find infinite answers to this and get enough points for the semester where you don't have to do work anymore. I will list a couple more possible answers below
