I also find a ratio of distances using vector direction, solve circle geometry with a tangent and radii to show angle ABC is half x, and calculate a sector angle and area using the arc length. Then I use the sine rule in a triangle to find AB, and finish with a longer vectors problem using point splits like a quarter and one third of vectors.
