We must remember one of the important properties of the secant lines to a circle.
If from a point outside the circle (Q) there are two secant lines that cross the circle at two points A and B for a secant line and C and D for another secant line, then the product of the segments of these two secant lines are equal to each other
Let's see the image given by the exercise with the notation of the property:
Applying the rule, we get,
In that sense, the correct answer is D. x= 11.
