Question

Circle C with chord DE perpendicular to diameter AB is shown. What is the length of FE?

Answer 1

Answer:

$FE=5\ units$

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

$FD=5\ units$

therefore

$FE=5\ units$
