Answer:

AC = 10

Explanation:

We can apply the properties of two secants intersecting outside a circle

(see attached for reference).

in our case, our formula will be

BC (BC + AB) = CD (CD + DE), which can be written as:

BC · AC = CD · CE

We are given:

BC = 6, DC = CD = 5, CE = 12

simply substitute the known values into the equation above

6 · AC = 5 · 12

AC = (5)(12) / 6

AC = 10
