Find the value of x. Assume that lines which appear to be tangent to the circle are tangent.
A) 5
B) 7
C) 9
D) 11

Answer:
C) 9
Step-by-step explanation:
Since tangents drawn from external point to a circle are e QQ ual in length.
therefore ,
5x - 6 = 3x + 12
5x - 3x = 12 + 6
2x = 18
x = 18/2
x = 9
