Answer:
[tex]FE=5\ units[/tex]
Step-by-step explanation:
we know that
If a diameter of a circle is perpendicular to a chord, then it bisects the chord
In this problem
AB is a diameter of circle C
The chord DE is perpendicular to the diameter AB
so
AB bisects the chord DE
That means
FD=FE
we have
[tex]FD=5\ units[/tex]
therefore
[tex]FE=5\ units[/tex]
