Question

X= 8 9 10
PLEASE HELP

Answer 1

8

Explanation:

The property of the two chords intersecting each other within the circle is

AO.OB=CO.OD

Where AB and CD are two chords as shown in the image attached with this.

Hence

here we are given that

AO = 10 , OB=4

CO=5 , OD=X

Hence

10*4=5*x

5x=40

dividing both sides by 5 we get

x=8

Hence our answer is 8
