JEE Math Practice Question
Two poles standing on a horizontal ground are of heights 5m and 10 m respectively. The line joining their tops makes an angle of 15º with ground. Then the distance (in m) between the poles, is :-
- A.$$5\left( {2 + \sqrt 3 } \right)$$
- B.$${5 \over 2}\left( {2 + \sqrt 3 } \right)$$
- C.$$10\left( {\sqrt3 - 1 } \right)$$
- D.$$5\left( {\sqrt3 + 1 } \right)$$
