Answer: Fourth Choice. x = 5
Concept:
Here, we need to know the idea of the intersecting chord theorem.
When two chords intersect each other inside a circle, the products of their segments are equal.
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
<u>Given information</u>
BE = 2
AE = 10
CE = 4
DE = x
<u>Given expression deducted from the intersecting chord theorem</u>
BE · AE = CE · DE
<u>Substitute values into the expression</u>
2 · 10 = 4 · x
<u>Simplify by multiplication</u>
20 = 4x
<u>Divide 4 on both sides</u>
20 / 4 = 4x / 4
Hope this helps!! :)
