If the height of a tower and the distance of the point of observation from its foot, both are increased by `10%`, then the angle of elevation of its top remains unchanged.

If the distance of a point from the tower is equal to the height of the tower , then find the angle of elevation of the top of the tower from that point .

If the distance of a point from the tower is equal to the height of the tower , then find the angle of elevation of the top of the tower from that point .

If the angle of elevation of a tower 18^(@) and the distance between top and point of observation is 4, Find the height to tower.

The respective ratio between the height of tower and the point at some distance from its foot is 5sqrt(3):5 .What will be the angle of elevation of the top of the tower ?

The Heights of two tower are 180 metres and 60 metres respectively. If the angle of elevation of the top of the first tower from the foot of the second tower is 60^(@) . Calculate the angle of elevation of the top of the second tower from the foot of the first.

The angle of elevation of the top of a tower is 30^(@) . if the height of the tower is doubled, then the angle of elevation of its top will also be doubled.

The angle of elevation of the top of an incomplete tower, at a point 40m away from its foot, is 45^(@) . How much more high the tower must be constructed so that the angle of elevation of its top at the same point be 45^(@) ?

The angle of elevation of the top of an incomplete tower, at a point 40m away from its foot, is 45^(@) . How much more high the tower must be constructed so that the angle of elevation of its top at the same point be 60^(@) ?

The angle of elevation of the top of a tower from the foot of a house, situated at a distance of 20 m from the tower is 60^(@) . From the top of the top of the house the angle of elevation of the top of the tower os 45^(@) . Find the height of house and tower.

The angle of elevation of the top of a tower from the foot of a house, situated at a distance of 20 m from the tower is 60^(@) . From the top of the top of the house the angle of elevation of the top of the tower os 45^(@) . Find the height of house and tower.
