In a movie theater 150 feet long, the floor is sloped so there is a difference of 30 feet between the front and back of the theater. What is the angle of depression?
----------
If 150 is the horizontal distance, the tangent(angle) = 30/150
If 150 is the distance on the floor, the sin(angle) = 30/150
