What is the correct way to represent the angle of depression from B to A (assuming A is on the ground, B is the top of the building)?
A.The angle between the line BA and the line segment AC, where C is the foot of the building.
B.The angle between the horizontal line through B and the line of sight BA.
C.The angle between the line BA and the line segment BC, where C is the foot of the building.
D.The angle at point A formed by the line BA and the horizontal ground.
Difficulty: Easy
