Directions: Study the following questions carefully and choose the rig...

Given, BC = 20 m
∠ACB = 30°
Total height of the telegraph post is (AB + CA) = ?
In Δ ABC, tan 30° =  AB / BC
1 / √3 = AB / 20
∴ AB = 20 / √3m
Now, cos 30º = BC / AC
√3 / 2 = 20 / AC
∴ AC = 40 /√3 m
So, AB + CA = (20 / √3) + (40 / √3) = (60 / √3)
= 20 √3 m
Hence, option B is correct.
