Question

Cd is congruent to df, e bisects df and cd= 14.2. find ef.

Answer 1

7.1 is the value of Ef where cd=df

Answer 2

7.1 units.

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=(df)/(2)` (e bisects df) ... (2)

Using (1) and (2) we get

`ef=(14.2)/(2)`

`ef=7.1`

Hence, the measure of ef is 7.1 units.
