P & Q are two points on the ground on either side of a pole. The angles of elevation of the top of the pole as observed from P & Q are 60 and 30 respectively and the distance between them is 84√3 m. What is the height (in m) of the pole?
Show answer & explanation
Correct answer: B
Explanation
The correct option is 2 i.e. 63.
3 + 1 → 4x
4x → 84√3
x → 21√3
√3x = 21√3 × √3 = 63
