Question

Ello, please help I’m a little stuck on how to go about solving this one. An explication would be great

Answer 1

B, D and F are midpoints
so
DB = 1/2 (AE)
BF = 1/2 (CE)
DF = 1/2(AC)
in this case you only need to find out DF = ?
 and you also know AC = 50
so
DF = 1/2 (AC)
DF = 1/2(50)
DF = 25
answer
DF = 25
