The horizontal distance between two trees of different heights is 60m. The angle of depression of the top of the first tree when seen from the top of the second tree is `45o` . If the height of the second tree is 80m, find the height of the first tree.

The horizontal distance between two towers is 60 metres. The angle of depression of the top of the first tower when seen from the top of the second tower is 30^(@) . If the height of the second tower is 90 metres. Find the height of the first tower. [Use sqrt(3)= 1.732 ]

The horizontal distance between two towers is 140m. The angle of elevation of the top of the first tower when seen from the top of the second tower is 30^(0). If the height of the second tower is 60m, find the height of the first tower.

The horizontal distance between two towers is 140m .The angle of elevation of the top of the first tower when seen from the top of the second tower is 30^(0). If the height of the second tower is 60m ,find the height of the first tower.

The horizontal distance between two poles is 15m. The angle of depression of the top of the first pole as seen from the top of the second pole is 30o .If the height of the second pole is 24m, find the height of the first pole.(sqrt(3)=1.732)

The horizontal distance between two poles is 15m. The angle of depression of the top of first pole as seen from the top of second pole is 30. If the height of the second pole is 24m, find the height of the first pole.Use v3=1.732)

The angle of elevation of the top of a building from the top and bottom of a tree are x and y repectively . If the height of the tree is h metre , then (in metre) the height of the building is

The distance between two towers is 140 m while seeing from the top if the second tower, the angle of elevation of first tower is 30^(@) .If the height of the second tower is 60 m, then find the height of the first tower.
