From what I know of trigonometry, a 180 degree viewer would be able to view flush to the door. A 290 degree viewer would be able to view behind itself! How is the 290 degree number arrived at?

It is angle of cone not the angle of view. Shape of the cone of door viewer is looking like 290 degree part of a circle. By this way its' gives you the maximum view. (Roughly 180 degree)
