Np
OpenStudy (michele_laino):
Sorry D is the mid point of EC?
OpenStudy (michele_laino):
ok! using theorem of Talete, we can conclude that FD is parallel to AC, the triangles ADF and AEC are similar for the third criterion, so AC=2*FD
OpenStudy (michele_laino):
namely AC=32

So is this what i would provide for number 7?
OpenStudy (michele_laino):
yes! please I write it better:
due to Talete's theorem, we can conclude that FD is parallel to AC, so triangle EFD and triangle AEC are similar each other, than since ratio ED/EC = 1/2 then also ratio FD/AC = 1/2, then AC= 2 FD=2*16=32

Wow your so high classed my teacher would know that i never got this on my own lol
