Criterion C - Communication The Advanced Version In most modern theaters, the floor is not flat. Using what you learned in your investigation of the simple version, briefly discuss why movie theater floors are built at an angle. Now, assume that the theater has a floor that makes a 25° angle with the horizontal. Everything else about the theater is the same. Find the best row, and compute how much greater your viewing angle is here, compared with the best seat in the theater with the flat floor. Name b 0° BBBB LLLLL 25° a More helpful suggestions: 1. Notice that in the simple version, when x changed our eyes simply moved back horizontally. Now, the height of our eyes also changes when x changes. Look at the triangle formed by the floor and level ground and write the coordinates of your eyes (distance back from the front and up from level ground) in terms of x. 2. Now write expressions for the distance from your eyes to the bottom of the screen (marked a) and eyes to the top of the…
