## calculating angle in circle

How to compute angle in a circle. Please see the layout to understand what I intend to compute? I have beginning of circle that is $(x_1,x_2)$. I have a factor on condition of circle that is $(x_2,y_2)$. Additionally I recognize the distance of circle that is R. How to compute the angle in between these 2 lines - - line beginning with beginning...
