The angle of elevation of the top of a tower as observed from a point on the horizontal ground is $$x$$. If we move a distance $$d$$ towards the flux of the tower, the angle of elevation increases to $$y$$, then the height of the tower is

The angle of elevation of the top of a tower at a distance $$500$$ meters from the foot is $$30^{\circ}$$. The height of the tower is 

If the angles of depression and elevation of the top of a tower of height $$h$$ from the top and bottom of a second tower and $$x$$ and $$y$$ respectively, then the height of the second tower is

The angle of elevation of a cloud from a point $$h$$ meters above the surface of a lake is $${30}^{o}$$ and the angle of depression of its reflection is $${60}^{o}$$. Then the height of the cloud above the surface of the lake is

The shadow of a stick of height $$1$$ metre, when the angle of elevation of the sun is $${ 60 }^{ o }$$, will be

The angle of elevation of a tower from a point on the ground is $${30}^{o}$$. At a point on the horizontal line passing through the foot of the tower and $$100$$ meters nearer to it, the angle of elevation is found to be $${60}^{o}$$, then the height of the tower is

If the angle of elevation of the sun at $$8:00$$ O'clock is $$\alpha$$ and at $$10:00$$ O'clock is $$\beta$$ then ______ holds.

The angles of depression of two boats as observed from the mast head of a ship $$50$$ metres high are $${45}^{o}$$ and $${30}^{o}$$. The distance between the boats, if they are on the same side of mast head in line with it, is

The angle of elevation of a stationary cloud from a point $$25\ m$$ above a lake is $$15^o$$ and the angle of depression of its image in the lake is $$45^o$$. The height of the cloud above the lake level is 

The angle of elevation of the top of the tower from the point $$a$$ meter away from the base of the tower is $$60^{\circ}$$. The height of the tower is _______ meter.
