Answer:
DF = 2.68
EF = 2.01
Explanation:
It is only possible to answer this question if the triangles are similar.
DF/AC = DE/AB . . . . . . . corresponding sides are proportional
DF = (AC/AB)DE . . . . . . . multiply by AC
DF = (4/2)(1.34) = 2.68
In like fashion, ...
EF = (BC/AB)DE = (3/2)(1.34) = 2.01
