If the angles of elevation of a tower from two points distant `a` and `b` from the base and in the same straight line with it are complementary, then the height of the tower is
(a)`a b`
(b) `sqrt(a b)`
(c) `a/b`
(d) `sqrt(a/b)`

If the angles of elevation of a tower from two points distant a and b (a > b) from its foot and in the same straight line with it are 30^@ and 60^@ , then the height of the tower is (a) sqrt(a+b) (b) sqrt(a b) (c) sqrt(a-b) (d) sqrt(a/b)

If the angles of elevation of the top of a tower from two points at a distance of 4m and 9m from the base of the tower and in the same straight line with it are complementary, find the height of the tower.

The angles of elevation of the top of a tower from two points at a distances a meter and b metres from the base of the tower and in the same straight line with it are complementary. Prove that the height of the tower is sqrt(a b) metres.

The angles of elevation of the top of a tower from two points at a distance of 4 m and 9 m from the base of the tower and in the same straight line with it are complementary. Prove that the height of the tower is 6 m.

The angles of elevation of the top of a tower from two points at a distance of 4 m and 9 m from the base of the tower and in the same straight line with it are complementary. Prove that the height of the tower is 6m.

The angle of elevation of the top of a tower from two points at a distance of 4 m and 9 m from base of the tower and in the same straight line with it are complementary. Prove that the height of the tower is 6 m. OR The angles of elevation of the top of a tower from two points at a distance of 4 m and 9 m from the base of the tower of the tower and in the same straight line with it are 60^(@)" and "30^(@) respectively. Find the height of the tower.

The angle of elevation of the top of a vertical tower from two points distance a and b from the base and in the same line with it, are complimentary .If theta is the angle subtended at the top of the tower by the line joining these points then sin theta =
