Start by using distributive property 4 x 3x and 4 x 2 then -5 x 7x and -5 x 5 Then you would take the total from 4 x 2 and 4 x 3x which equals 12x+8 and subtract it by the total for -5 x 7x and -5 x 5 which equals -35x-25 Next you would combine like terms -35x plus 12x and 8-25 -23x-17 would be your answer
I'm going to be honest the question is a little confusing cause of the beginning, but if you're looking for which angles are actually congruent it's ∠GAC ≅ ∠HFD
