Best ResponseYou've already chosen the best response.0k i don't understand why i am getting this wrong. you find the equation of the first plane by finding vectors AB and AC, then take the cross product, which i got to be n=<42,70,42> then just use the <17,23,5> from the second equation and plug into (a dot b) / mag of a * mag of b = inverse cos to find theta which i got to be 114.52 but for some reason it keeps coming up wrong
