Answer : The correct option is (4) x = 5
Explanation :
As we know that the tangents from a common point to a circle that is outside a circle are equal in length.
As we are given that:
Length of tangent 1 = 9
Length of tangent 2 = 2x - 1
According to the circle theorem:
Length of tangent 1 = Length of tangent 2
So,
9 = 2x - 1
2x = 9 + 1
2x = 10
x = 5
Therefore, the value of x is 5.
