Answer 2

however there are multiple choices I went with choice D).

A) the angle of elevation from the plane to the tower
B) the angle of depression from the plane to the tower
C) the angle of depression from the tower to the plane

Answer 3

B because the plane is already in the air, and if it were to go downward toward the tower it would be the angle from the plane to the tower as it depresses
