A pole casts a shadow of length 2√3 m on the ground when the sun's elevation is 60°. The height of the pole is
A. 4J m
B. 6 m
C. 12 m
D. 3 m
In the above figure, let AB be the pole and BC be its shadow. Given that BC = 2√3 m and ∠ACB = 60°. We have to find AB.
AB = 2√3 × √3 = 2 × 3 = 6 m
Hence the correct choice is B.
