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
\(cd\cong df\)
\(cd=df=14.2\) (Measure of congruent segments are equal) ... (1)
\(de=ef=\dfrac{df}{2}\) (e bisects df) ... (2)
Using (1) and (2) we get
\(ef=\dfrac{14.2}{2}\)
\(ef=7.1\)
Hence, the measure of ef is 7.1 units.
