Best ResponseYou've already chosen the best response.1EC = EI (let be x) HI = HF = HG = radius = 7 EH = FE + HF = 18+7 = 25 look at the triangle of HIE (it is a right triangle), use the pythagorean theorem to get EI so, EI^2 = EH^2  HI^2 EI^2 = 25^2  7^2 solve for HI

Best ResponseYou've already chosen the best response.1i already supposed EI be x so, x^2 = 25^2  7^2 solve for x

Best ResponseYou've already chosen the best response.1from information above, HG = 7 nah, HI = HF = HG = radius = 7

Best ResponseYou've already chosen the best response.1EI^2 = 25^2  7^2 EI^2 = 625  49 EI^2 = 576 EI = sqrt(576) = 24

Best ResponseYou've already chosen the best response.1because EC = EI so, EC = 24

Best ResponseYou've already chosen the best response.125^2 = 25 x 25 = 625 note : ^ sign means square
