The upper `3/4` th portion of a vertical pole subtends an angle `theta` such that tan `theta=3/5` at a point in the horizontal plane through its foot and at a distance 40m from the foot. Find the possible height of the vertical pole.

10. The upper 3/4 portion of a vertical pole subtends an angle tan^-1(3/5) at the point in the horizontal plane through its foot. The tangent of the angle subtended by the pole at the same point is

The angle of elevation of the top of a tower from a point 40 m away from its foot is 60^(@) . Find the height of the tower.

A tower subtends angle theta, 2theta, 3theta at the three points A,B and C respectively lying on a horizontal line through the foot of the tower. Then AB/BC is equal to

A tower of height b subtends an angle at a point 0 on the ground level through the foot of the tower and at a distance a from the foot of the tower. A pole mounted on the top of the tower also subtends an equal angle at 0. The height of the pole is

A tower subtends an angle of 60^(@) at a point on the plane passing through its foot and at a point 20 m vertically above the first point, the angle of depression of the foot of tower is 45^(@) . Find the height of the tower.

From a point on the ground at a distance a from the foot of a pole, a ball is thrown at an angle of 45^@ , which just touches the top of the pole and strikes the ground at a distance of b , on the outer side of it. Find the height of the pole.

The angle of elevation of the top of a tower. from a point on the ground and at a distance of 160 m from its foot, is fond to be 60^(@) . Find the height of the tower .

A vertical pole with height more than 100 m consists of two parts, the lower being one-third of the whole. At a point on a horizontal plane through the foot and 40 m from it,the upper part subtends an angle whose tangent is 1/2 What is the height of the pole

The electric pole subtends an angle of 30^(@) at a point on the same level as its foot. At a second point 'b' metres above the first, the depression of the foot of the tower is 60^(@) . The height of the tower (in towers) is equal to

The upper part of a tree broken over by the wind makes an angle of 60^(@) with the ground and the horizontal distance from the foot of the tree to the point where the top of the tree meets the ground is 10 metres. Find the height of the tree before broken.
