Not to scale. Angles and distances for example only

Known:

radius of large ball (r1)

radius of small ball (r2)

line BC = r1 + r2

line AD

line AB

point A

point B

point D

angle BAC

Find:

lind CD

line AC = line AD + line CD

point C

Anyone know what formula I would use to find point c, based on what info I DO have? Basically I know the length of two sides, and an angle (but not the angle between them). If I can find the length of the other side I can then find the point myself.

Thanks!
