If I have the following circle, with centre in red and a random point in the circle in blue. I know the radius ,r, length of d, and the angle p:
I then create a a new green point and I know the length to the new green point (length=q) from the blue point. Now What I want to calculate is where the line q intersects the circle and at what angle it meets the tangent of the radius i.e.: the coordinates of the orange point and angle z, given that I also know k:
What is the quickest/most straightforward way to get orange point and z?
This is my first question so if any clarifications required please let me know.
