In a cubicul hall `ABCDPQRS` with each side `10m, G` is the centre of the walls `BCRQ and T` is the midpoint of the side `AB,` the angle of elevation of `G` at the Point `T` is

A T.V. tower stands vertically on the side of a road. From a point on the other side directly opposite to the tower the angle of elevation of the top of tower is 60^@ . From another point 10 m away from the point, on the line joining the point of the foot of the tower, the angle of elevation of the top of the tower is 30^@ . THe width of the road is......

Two buildings are facing each other on either side of a road of width 12m. Form the top of the first building , which is 10m. High, the angle of elevation of the top of the second is 60^@ . What is the height of the second building?

P is any point on the side BC of a triangle ABC . P is joined to a. If D and E are the midpoints of the sides AB and AC respectively and M and N are the midpoints of BP and CP respectively then quadrilateral DENM is

A flagstaff stands in the centre of a rectangular field whose diagonal is 120 m. It subtends angles of 15^@ and 45^@ at the midpoints of the sides of the field. The height of the flagstaff is
