Sorry for the really sloppy graph. They are suppose to be two circles, it's just that I don't know how to draw circles with my graph sketcher.
Note: Figure not drawn to scale
This is on page 839 of the OG Book.
In the figure below, the two circles are tangent (what is a tangent?) at point B and AC=6. If the circumstances of the circle with center A is twice the circumference of the circle with center C, what is the length of line segment BC?
Thanks in advance
