The angle of elevation of the Sun, if the length of the shadow of a tower is 3 times the height of the pole, is
150°
30°
60°
45°
Explanation for correct option:
Let
Ab=h,Then,BC=x=h3
In ∆ABC
tanθ=ABBC⇒=hh3⇒θ=tan-113=30°
Hence, the correct option is B.
If the length of a shadow cast by a pole is √3 times the length of the pole, then the angle of elevation of the sun is
