Answer 1

Answer:

x = 5 unit

Step-by-step 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 = $\frac{12 times 3}{4}$

Or,      X + 4 = $\frac{36}{4}$

Or,      X = 9 - 4

∴         X = 5 unit
