A pole stands vertically on the ground with the help of a 12-metre steel wire tied to its top and affixed on the ground. If the steel wire makes an angle of 30° with the horizontal ground, then the height of the pole is equal to:
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1. i.e. 6 meters
Given that
The height of a pole H = 12 m
The steel wire makes an angle of 30° with the horizontal
⇒ Sin 30º = H/12
⇒ 1/2 = H/12
⇒ H = 6 m
Hence, the height of the pole is 6 meters
