Answer:
7.1 units.
Step-by-step explanation:
It is given that cd is congruent to df, e bisects df and cd= 14.2.
We have to find the measure of ef.
Using given information we get
[tex]cd\cong df[/tex]
[tex]cd=df=14.2[/tex] (Measure of congruent segments are equal) ... (1)
[tex]de=ef=\dfrac{df}{2}[/tex] (e bisects df) ... (2)
Using (1) and (2) we get
[tex]ef=\dfrac{14.2}{2}[/tex]
[tex]ef=7.1[/tex]
Hence, the measure of ef is 7.1 units.
