Question

Anyone who knows please help!!!!

i tried to solve this on my own but it's not happening rip

Answer 1

Since it’s isosceles FE and ED are both equal to 6 so you do

FD^2=FE^2+ED^2
=6^2+6^2
=72
FD=6roots2

Answer 2

13.5

Explanation:

the answer is 13.5, because you do the proportionate equations of 6/4 = x/9, and then you cross multiply to get 4x=54, and then you isolate x, so the answer is 13.5
