forgive me if this isn't the right place to ask this question but I am trying to figure out the value of theta along a line tangent to a circle from a starting position on the circle to an ending one outside of the circle. I have constructed an image to explain what I am trying to do.
I know the value of the circles radius, the arc-length between the start and end point, and the height of the end point. With this information is it possible to determine the angle in question?
Thanks for the help! (Also not sure what to tag this question with)
