Word Practice Problem
Martin Scorsese has decided to film the first text-to-screen adaptation of Catcher in the Rye. He wants the first dance floor scene at the club with the three women to be in slow motion with a warp stabilizer. In coordination of how he imagines it, he wants the camera to start at angle A of 45˚, the move left 21in to angle B of an unknown angle. He then wants to come around the dancing pair 40 inches downward to angle C at another unknown angle. Stuck, Scorsese is unsure of the angle measurements angle B and C should be, as well as the distance between angle A and C. Use trigonometry to help Scorsese find these missing parts and complete the scene set up.
Solving: (using Law of Sines)

According to Law of Sines, Scorsese should film at angle B of about 113˚, angle C at about 22˚, with the distance between angles A and C at about 52in.
