The angle of elevation of the top of a tower from a point $$20m$$ away from its base is $${60^ \circ }$$. The height of the tower is-

A vertical to stands on a horizontal plane and is surmounted by a vertical flag staff of height 6 meters. At point on the plane angle of elevation of the bottom and the top of the flag staff are respectively $${ 30 }^{ \circ  }and60^{ \circ  }$$. Find the height of tower.

From the top of a cliff $$25 \ m$$ height, the angle of the elevation of the the top of tower is found to be equal to the angle of depresion of the foot of the tower. The height of the tower is

From the top of a tower $$100m$$ high, the angels of depression of the bottom and the top of a building just opposite to it are observed to be $${60^ \circ }$$ and $${45^ \circ }$$ respectively, then height of the building is: 

The angle of elevation of the sun, when the length of the shadow of a tree is $$\sqrt{3}$$ times the height of the tree, is

If a tower $$30\ m$$ high, casts a shadow $$10\sqrt{3}\ m$$ long on the ground, then what is the angle of elevation of the sun?

The length of a shadow of a vertical tower is $$\dfrac{1}{\sqrt{3}}$$ times its height. The angle of elevation of the sun is:

From the top of a cliff  $$24\mathrm { mt }$$  height, a man observes the angle of depression of a boat is to be  $$60 ^ { \circ } .$$  The distance of the boat from the foot of the cliff is

A tower is $$50\sqrt{3}$$ m high. The angle of elevation of its top from a point 50 m away from its foot has measure............degree

If a pole  $$12\ { m }$$  high casts a shadow  $$4\sqrt { 3 }\ { m }$$  long on the ground then the angle of elevation is
