I think that the answer is four because it makes much more sense but five is not greater than five or less than five so I don’t know. Try four though sorry if it’s wrong though.
Y= 40 explanation don’t want to just trust me it’s 40
Using the equations for tangent and secant lines:
Let the unknown length of the line inside the circle = y
6^2 = 3 x (y+3)
Simplify:
36 = 3y+9
Subtract 9 from both sides:
27 =3y
Divide both sides by 3:
Y = 9
Now add to get x:
X = 9 + 3 = 12
X = 12
