As observed from the top of a light house, 100m above sea level, the angle of depression of a ship, sailing directly towards it, changes from `30o` to `45o` . Determine the distance travelled by the ship during the period of observation.

As observed from the top of a light house, 100 m high above sea level, the angles of depression of a ship, sailing directly towards it, changes from 30^(@)" and "90^(@) . then distance travelled by ship is

As observed from the top of a 150 m tall light house, the angles of depression of two ships approaching it are 30^@ and 45^@ . If one ship is directly behind the other, find the distance between the two ships.

An observer on the top of a cliff, 200 m above the sea-level, observes the angles of depression of the two ships to be 45^(@) and 30^(@) respectively. Find the distance between the ships, if the ships are on the same side of the cliff,

As observed from the top of a 75 m high lighthouse from the sea-level, the angles of depression of two ships are 30o and 45o . If one ship is exactly behind the other on the same side of the lighthouse, find the distance between the two ship.

An observer on the top of a cliff, 200 m above the sea-level, observes the angles of depression of the two ships to be 45^(@) and 30^(@) respectively. Find the distance between the ships, if the ships are on the opposite sides of the cliff

As observed from the top of a 100 m high lighthouse from the sea level, the angles of depression of two ships are 30^@ and 45^@ If one ship is exactly behind the other one on the same side of the lighthouse, find the distance between the two ships.
