A point on the ground is 5m away from the foot of a vertical wall 7 m high, Calculate, correct to the nearest degree, the angle of depression of the point from the top of the wall

A.
36^{o} 
B.
44^{o} 
C.
46^{o} 
D.
54^{o}
Correct Answer: Option D
Explanation
θ= angle of depression of the point from the top of the wall
(tantheta = frac{7}{5}=1.4; theta = tan^{1}(1.400)
theta = 54.4^{circ}; theta = 54^{circ}) to the nearest degree
