From the top of a light house, 80 meters high, two ship on the same side of light house are observed. The angles of depresion of the ships as seen from the light house are found to be of `45^(@) and 30^(@).` Find the distance between the two ships. (Assume that the two ships and the bottom of the lighthouse are in line )

Text Solution

Verified by Experts
