The angle of elevation of the top of a temple when observed from a point on the horizontal line through the foot of the temple is found to be 30^@ .By advancing 200m towards the temple the angle of elevation of the top of the temple is found to be 60^@ .Find the height of the temple.

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.
