Ok I need help finding the angle and I attached a crude picture of the drawing. just to clarify the circles are tangent to one another and the ray that is created by the angle and the radii are perpendicular to the top of the ray. The radii are 2inches and 4 inches respectively.

The only thing I don't know is how to calculate the hypotenuse and/or the top ray to finish the problem.

Thank you in advance
