Answer:
Step-by-step explanation:
Theorem: A line drawn from the center perpendicular to the chord bisects the chord.
By the Theorem above, Point E and F bisects CD and AB into 6 Units each as seen in the diagram.
Therefore:
|FB|=6 Units
In Right Triangle OED, applying Pythagoras Theorem
[tex]10^2=6^2+|OE|^2\\|OE|^2=100-36\\|OE|^2=64\\|OE|^2=8^2\\|OE|=8 \:Units[/tex]
Therefore:
