Two ships are sailing in the sea on the two sides of a lighthouse. The angles of elevation of the top of the lighthouse as observed from the ships are 45° and 60° respectively. If the lighthouse is 81 m high, then the distance between two ships is:
1
\(\frac{(1 + \sqrt3)}{81\sqrt3}\) m
2
\(\frac{[81(1 + \sqrt3)]}{\sqrt3}\) m
3
\(\frac{81}{\sqrt3}\) m
4
\(\frac{(1 + \sqrt3)}{\sqrt3}\) m
