if XY||DF \[\frac{EX}{XD}=\frac{EY}{YD}=\frac{8}{DF}\]

  • xapproachesinfinity
we know that EY is congruent to YD EY=YD therefore: \[1=\frac{8}{DF}\]

oh mistake i forgot how this theorem works, after checking online it should be \[\frac{EX}{ED}=\frac{EY}{EF}=\frac{8}{DF}\] \[ED=2EX \Longrightarrow \frac{1}{2}=\frac{8}{DF} \Longrightarrow DF=16\]
