The angle of depression of a car C, from the top of the building of height 100m is

a) Calculate the distance between the car and the foot of the building?

b) Calculate the angle of elevation of the top of the building from a point D which is 100m from C as shown?​

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
