Answer 1

The answer is 48 NOT 12

Explanation:

Answer 2

Option (2)

Explanation:

By using theorem of intersecting secant and tangent at a point outside a circle.

PB × PA = (PQ)²

Since, PB = 2 units

PA = (PB + AB)

= (2 + 6)

= 8 units

PQ = x units

Therefore, by substituting these values,

2 × 8 = x²

`x^(2) = 16`

Therefore, Option (2) will be the correct option.
