Answer:
option A, x² = 12
Step-by-step explanation:
In this question a secant has been drawn from an external point, bisecting the circle in two parts, one is 6 and second is 2 units.
From the same point a tangent has been drawn of length = x
By theorem of secants and tangent.
x² = 6 × 2 = 12
Therefore, option A, x² = 12 is the answer.
