Any ideas on the point coordinates of the intersection of the circle?
Sure (I don't know if the symbols I'm using will come across):
Sin(:) x Hypotenuse = side opposite (which in cartesian coordinates gives
you the "y")
Then pythagorean theorem to find the side adjacent (which is "X")
Sin(45) x 36 = 25.45584412
Since the angle is 45: both coordinates will be equal:
(25.45584412, 25.45584412)
