Answer 1

x = 5 unit

Explanation:

The given figure represent the theorem of circle,

It two chords of circle intersect outside or inside when produce, then

AP × PB = DP × PC

SO , from given data we can find the X

Now, (X + 4) × 4 = (9 + 3) × 3

Or, X + 4 =
`(12 times 3)/(4)`

Or, X + 4 =
`(36)/(4)`

Or, X = 9 - 4

∴ X = 5 unit
