Answer:
Option (2)
Step-by-step 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
[tex]x^{2} = 16[/tex]
Therefore, Option (2) will be the correct option.
