A flagstaff stands vertically on a pillar, the height of the flagstaff being double the height of the pillar. A man on the ground at a distance finds that both the pillar and the flagstaff subtend equal angles at his eyes. The ratio of the height of the pillar and the distance of the man from the pillar is

A flag staff stands vertically on a pillar. The height of the flag staff being double the height of the pillar. A man on the ground at a distance finds both pillar and the flag staff subtends equal angle ' theta ' at his eye then theta =

A tower of height 5m and a flagstaff on top of the tower subtend equal angles at a point on the ground, distance 13m from the base of the tower. The height of the flagstaff is

A 6 -ft tall man finds that the angle of elevation of the top of a 24 -ft-high pillar and the angle of depression of its hase are complementary angles. The distance of the man (in metres) from the pillar is

From two points on the ground and lying on a straight line through the foot of a pillar, the two angles of elevation of the top of the pillar are complementary to each other. If the distances of the two points from the foot of the pillar are 12 metres and 27 metres and the two points lie on the same side of the pillar, then the height (in metres) of the pillar is:

A post stands on the top of a pillar 40ft high. The elevations of the tops of the pillar and the post are respectively 30^@ and 45^@ to an observer standing on the horizontal line from the foot of the pillar. Find the lenght of the post and the distance of the observer from the pillar.
