The angle of depression of two ships form the top of light house situated at 60 m height from sea level, 30° and 45°. If two ships are on the same side of the light house, then the distance between two ships is -
1
\((60 +\sqrt 3)\)m
2
\(60\sqrt 3\) m
3
\(60(\sqrt 3 - 1)\) m
4
60\((\sqrt 3 + 1)\) m
