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 36o
  • B 44o
  • C 46o
  • D 54o

The correct answer is D. 54o

θ= angle of depression of the point from the top of the wall

\(tan\theta = \frac{7}{5}=1.4; \theta = tan^{-1}(1.400)\

\theta = 54.4^{\circ}; \theta = 54^{\circ}\) to the nearest degree
