Question
If the height of a pole is 2√3 metres and the length of its shadow is 2 metres, find the angle of elevation of the sun.
Answer: Option B
LET AB BE THE POLE AND AC BE ITS SHADOW. LET ANGLE OF ELEVATION, ∠ACB = θ. THEN, AB = 2√3M, AC = 2 M. TAN θ = AB/AC = 2√3/2 = √3 θ = 60°. SO,THE ANGLE OF ELEVATION IS 60°
