How can a cubic Bezier curve be constructed to have a tangent to a circle?

Can anyone describe a tangency of Bezier curve such as below image?

This is a pretty vague request. Can you be more specific?

The circle is construct first.

Then how construct a Bezier curve, say, a cubic Bezier curve, which has its tangent to the circle?

I hope you understand.
