AB corresponds to FG
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
So FG/AB = 6/8 = 0.75 is the number you multiply each side length in the larger pentagon to get the corresponding side length in the smaller pentagon

jim_thompson5910Best ResponseYou've already chosen the best response.0
8 times 0.75 = 6

notice how FJ corresponds to AE
 one year ago

jim_thompson5910Best ResponseYou've already chosen the best response.0
and FJ = 6 So AE = FJ/0.75 = 6/0.75 = 8 which means AE = 8
