Answer:
8
Step-by-step 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
