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 ?

From the top of a lighthouse, the angles of depression of two ships on the opposite sides of it are observed to be a and p. If the height of the lighthouse is h m etres and the line joining the ships passes through the foot of the lighthouse, show that the distance betw een the ships is (h(tan alpha + tan beta))/(tan alpha tan beta)

The height of a light house is 20 above sea level. The angle of depression (from the top of the lighthouse) of a ship in the sea is 30^0 . What is the distance of the ship from the foot of the light house?

The angles of depression of two ships from the top of a light house are 45^(@) and 30^(@) towards east. If the ships are 200 m apart, find the height of light house.

The angles of depression of two ships from the top of a lighthouse are 45^@ and 30^@ . If the ships are 120 m apart, then find the height of the lighthouse.

From a top of a lighthouse, an observer looks at the ship and find the angle of depression to be 45^(@) . If the height of the lighthouse is 1000m , then how far is that ship from the lighthouse.

From the top of a lighhouse, the angles of depression of two ships on the opposite sides of it are observed to be 30^(@) and 60^(@) . If the height of the lighthouse is h meters and thhe line joining the ships passes through the foot of the lighthouse. show that the distance between the ships is (4h)/(sqrt(3)) m.

From the top of a lighthouse 70 m high with its base at sea level, the angle of depression of a boat is 15^(@) . The distance of the boat from the foot of the lighthouse is :
