the distance between two vertical poles is 100m and the height of one of them is double the other. The angle of elevation of their tops at the middle point of the line joining their feet are complimentary. Find the height.

The distance between two poles of the same height standing on the same plane is 100m.The angles of elevation of the tops of the two poles from a point lying on the line joining the base-points of the poles are found to be 30^@ and 60^@ respectively.Find the heights of the poles and the position of the point.

If the angle between two lines is pi/4 and slope of one line is 1/2,find the slope of the other line.

From a point which is 200sqrt2 m away from the base of a temple the angle of elevation of the top of the temple is 45^@ .Find the height of the temple and the slanting distance between the top of the temple and the point.

Two poles of equal heights are standing opposite to each other on either side of the road which is 80m wide. From a point between them on the road the angles of elevation of the top of the poles are 60° and 30° respectively. Find the height of the poles .

There are two poles on each on either bank of a river just opposite to each other.One pole is 60m high.From the top of this pole the angles of depression of the top and the foot of the other pole are 30° and 60° respectively. Find the width of the river and the height of the other pole.

Two pillars of equal height stand on either side of a road which is 150m wide. At a point on the road between the pillars the angle of elevation of the top of the pillars are 60° and 30°. Find the height of each pillar and the position of the point on the road.
