The <em>correct answer</em> is:
A) A tangent is never a secant.
Explanation:
A tangent is a line that touches a circle in exactly one point. A secant is a line that touches a circle in two different points.
Since a tangent only touches once and a secant touches twice, there is no way a tangent can be a secant.
the answer is 360 because if you take a third you will have 120 then if you take half of that then you get 60
8 because 2 times 5 is ten
