Hey! This is the Pythagorean theorem aka my favorite subject in math! Anyways the answer is FALSE. Here’s why. When finding one of the legs (a or b) you have to do a^2-c^2 (or b^2-c^2) I did 9 squared and got 81 minus 14 squared (196) and got 196-81=115. Square root of 115 is 10.72- making this false.
