Finding the length of segment DF,
then find the length of segment EF
Using the similar triangles,
Triangle ABC = Triangle DEF
AB / DE = AC / DF = BC / EF
2 / 1 . 34 = 4 / DF = 3 / EF
Solving 2 / 1 . 34 = 4 / DF
cross - multiply, we have:
2 X DF = 4 X 1. 34
2 DF = 5. 36
DF = 5 . 36 / 2
DF = 2 .68
Solving 2 / 1 . 34 = 3 / EF
cross - multiply, we have:
2 x EF = 3 X 1. 34
2 EF = 4 .02
EF = 4. 02 / 2
EF = 2. 01
