A person in a balloon, who has ascended vertically from flat land at the sea level,observes the angle of depression of a ship atanchor to be `30^@`. After descending vertically 600 metres, he finds the angle of depression tobe `15^@`. The horizontal distance of the ship from the foot of ascent in metres is

A person in aballoon, who has ascended verticallly from flat land at the sea level, observes the angle of depression of a ship at anchor to be 30^(@) . After descending verticallly 600 metres, he finds the angle of depression to be 15^(@) . The horizontal distance of the ship from the foot of ascent in metres is

From the top of a light -house at a height 20 metres above sea -level,the angle of depression of a ship is 30^(@) .The distance of the ship from the foot of the light house is

The angle of depression of a ship as observed from the top of a lighthouse is 45^(@) . If the height of the lighthouse is 200 m , then what is the distance of the ship from the foot of the lighthouse ?
