From a light house the angles of depression of two ships on opposite sides of the light house are observed to be `30^@ and 45^@` If the height of the light house is h metres, the distance between the ships is

From the top of a light house, the angles of depression of two ships on the opposite sides of its are observed to be alphaa n dbeta . If the height of the light house be h metres and the line joining the ships passes through the foot of the light house, show that the distance between the ship is h(tanalpha+tanbeta)/(tanalphat a nbeta)

From the top of a light-hours, the angles of depression of two ships on the opposite sides are observed to be 30^(@)" and "45^(@) . If the height of the light-house, is 90 m and the line joining the two ships passes through the light- house, then find the distance between the ships.

Two ships are there in the sea on either side of a light house in such a way that the ships and the light house are in the same straight line. The angles of depression of two ships are observed from the top of the light house are 60^@ and 45^@ respectively. If the height of the light house is 200 m, find the distance between the two ships. (U s e\ \ sqrt(3)=1. 73)

From the top of a light house, the angles of depression of two stations on opposite sides of it at a distance a apart are alpha and beta . Find the height of the light house.

As observed from the top of a 80 m tall lighthouse, the angle of depression of two ships, on the same side of the light house in horizontal line with its base, are 30^(@) and 40^(@) respectively . Find the distance between the two ships. Given your answer correct to the nearest metre

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.

Two ships are sailing in the sea on the two sides of a lighthouse. The angle of elevation of the top of the lighthouse is observed from the ships are 30° and 45° respectively. If the lighthouse is 100 m high, the distance between the two ships is:

At one side of a road, there os a house and on the other side there is a tower. House and tower are on the same horizontal plane. The angle of depression of the top and foot of the house, from the top of the tower are 30^(@)" and "45^(@) respectively. If the height of the house is 10 m, then find the distance between the house and the tower.

As observed from the top of a 75m tall light house, the angles of depression of two ships are 30^@ and 45^@ . If one ship is exactly behind the other on the same side of the light house, find the distance between the two ships.

Two points A and B are on the same side of a tower and in the same straight line with its base. The angles of depression of these points from the top of the tower are 60^(@)" and "45^(@) respectively. If the height of the tower is 15 m, then find the distance between these points.
