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
36.87\(^o\)
39.70\(^o\)
51.34\(^o\)
53.13\(^o\)
Correct answer is C
Tan \(x^o = \frac{100m}{80}\)
Tan \(x^o = Tan^{-1} 1.25\)
x = 51.34\(^o\)
