A man observed the top of a tower at a distance `a` from its base
at an angle of elevation `30^circ`. He saw the top of a tower at an
angle of elevation `60^circ` from a point at the distance `b` from the
base, Prove that the height of the tower `h=sqrtab`

A man observed the top of a tower at a distance a from its base at an angle of elevation 60^@ . He saw the top of the tower at an angle of elevation 30^@ from a point at the distance b from the base.Prove that height of the tower h= sqrt(ab)

A boy sees the top of a tówer with an angle of elevation. 60^circ . Stepping 20metres back, he sees the same top with an angle of elevation 30^circ . Draw a rough figure and calculate the height of the tower.

A man 1.7 metres tall stands 10 metres away from the foot of a tree, and he sees the top of the tree at an angle of elevation 40^circ . How tall is the tree?

A boy viewed the top of a tree at anangle of elevation 30^@ . He moved 10 m towards the tree and saw the top of the tree ant the angle 60^@ Find the height of the tree.

From the top of a tower, the angle of depression of a point on the ground is 60^@ . If the distance of this point from the tower is 1/(sqrt3+1) m then the height of the tower is

A child stands 30 metres away from the foot of a telephone tower, sees the top of the tower at an angle of elevation 30^circ . Stepping some distance towards the tower, sees it at an elevation of 45^circ a) What is the height of the tower? b) How much distance did he walk?

From the top of a building 15 meter high, one sees the top of another taller building at an angle of elevation of 70^circ and bottom at an angle of depression of 40^circ a) Draw a rough figure and mark the measurements given. b) Find the height of the taller building.
