Answer:

C. 56

Explanation:

angles - exterior.

the angle at the intersection of the secants (yes, also a tangent is a secant, it is just that both intersection points with the circle are "falling" into the same point) is half of the outside arc angle minus the inner arc angle.

so,

72 = (200 - x)/2

144 = 200 - x

-56 = -x

x = 56
