So I need help and I don't know what I did wrong. I got 35648 and then when I insert it into my calculator I got 35648 and then I got 188.0 and I don't see an answer choice for it and I'm confused about what I did wrong. Can someone please give me an explanation? Btw this is about the Pythagorean Theorem aka square root
