Find the lengths of de and ef. note: segments bc and df are parallel.

DE=9

FE=15

Step-by-step explanation:

Triangle EBC is similar to triangle EDF.

Therefore

Expand to get;

Group similar terms:

Divide both sides by 13 to get:

We substitute to get:

DE= 5x-3+4

DE=5*2-3+4

DE=10-1=9

Also,

FE=4x+2+5

FE =4*2+2+5

FE=8+7

FE=15
