Answer:

Step-by-step explanation:

The product of segment lengths to the near and far circle intersection points is the same for both "secants". AD is a tangent, so the two intersection points are the same point. This gives ...

AD² = AB·AC

144 = AB(AB +10)

We can add 25 to complete the square.

169 = (AB +5)² . . . write as a square

13 = AB +5 . . . . . . positive square root

8 = AB . . . . . . . . . .subtract 5
