Suppose that a movie theater has a screen that is 29 feet tall. When you sit down, the bottom of the screen is 8 feet above your eye level. The angle formed by drawing a line from your eye to the bottom of the screen and another line from your eye to the top of the screen is called the viewing angle. In the figure at right, 0 is the viewing angle. Suppose that you sit x feet from the screen. The viewing angle 0 is given by the function below the figure. Complete parts (a) through (c). 8 0(x) = tan x feet -1 tan 29 feet 18 feet
