I first prove with side angle side that in a quadrilateral AC equals BD, using AB equals CD and angle ABC equals angle BCD. Next I handle a hexagon/parallelogram setup, then derive expressions with cosine rule and end up with cos P B Q. I also show how to get two possible x values from similar triangles, then finish with trig graph transformations and a vectors ratio midpoint question. No specific action is requested from you."}
