A stationary boat is observed from a height of 100m. If the horizontal distance between the observer and the boat is 80m, calculate, correct to two decimal places, the angles of depression of the boat from point of observation
36.87o
39.70o
51.34o
53.13o
Correct answer is C
Tan xo=100m80
Tan xo=Tan−11.25
x = 51.34o
