Brandon uses the following reasoning to find the length c of the third side in the triangle shown. The two legs of the triangle are 5 and 12. I know by the Pythagorean Theorem that 5 + 12 = , I calculate 5 + 12 = 25 + 144 = 169. My calculator says that the square root of 169 is 13, so c = 13." 67 249 12 Which statement is true about this reasoning? A. Brandons reasoning is conect. B.
