The angles of elevation of the top of a tower from two points at distance m and n metres are complementary. If the two points and the base of the tower are on the same straight line, then the height of the tower is

What is the height of a tower if the angles of elevation of its top from two points $$x$$ and $$y$$ at distance of $$a$$ and $$b$$ respectively from the base and on the same straight line with the tower, are complementary?

The angle of elevation of the sun when the length of the shadow of a pole is $$\sqrt 3$$ times the height of the pole is

A vertical pole breaks due to storm and the broken part bends so that the top of the pole touches the ground, making an angle of $$30^{\circ}$$ with the ground. The distance from the foot of the pole to the point where the top touches the ground is $$10 \text{ m}$$. The height of the pole is

The angles of elevation of an artificial satellite measured from two earth stations are $$30^0$$ and $$60^0$$ respectively. If the distance between the earth stations is 4000 km, then the height of the satellite is

The Qutub Minar casts a shadow $$150~ \text{m}$$ long, at the same time the Vikas Minar casts a shadow $$120 ~\text{m}$$ long on the ground. If the height of the Vikas Minar is $$80~ \text{m}$$, find the height of the Qutub Minar.

The distance between the tops of two trees $$20\ m$$ and $$28\ m$$ high is $$17\ m$$. The horizontal distance between the two tree is

The angles of elevation of the top of a vertical tower from two points. 30 metros apart, and on the same straight line passing through the base of tower, are $$30^0$$ and $$60^0$$ respectively. The height
of the tower is

A man observes the elevation of a tower to be $$30^0.$$ After advancing 11 cm towards it, he finds that the elevation is $$45^0.$$ The height of the tower to the nearest metro is
