A pole $$15$$ m long rests against a vertical wall at an angle of $$\displaystyle 30^{\circ}$$ with the ground How high up the wall does the pole reach?

In the given figure given, $$\beta$$ is _____ 

In the given figure, $$\alpha$$ is _____ 

the shadow cast by a tower is 30 m long when the elevation of sum is $$\displaystyle 30^{\circ}   $$ If the elevation of sum is $$\displaystyle 60^{\circ}   $$  then the length of the shadow is 

The angle of elevation of the top of a tower at a horizontal distance equal to the height of the tower from the base of the tower is 

The length of the shadow of a pole is $$\displaystyle \sqrt{3}   $$ times its height  The elevation of the sum must be 

From the point B a perpendicular BD is drawn on AC. If $$\cos 30^o=0.8$$, find the length of AD.

In case of angle of elevation, the observer has to look _____ to view the object. 

From a point P on a level ground, the angle of elevation of the top tower is $$30^{\circ}$$. If the tower is $$100\ m$$ high, the distance of point P from the foot of the tower is:

In angle of elevation the observer looks ____ to view the object whereas in angle of depression he looks ____ to view object.
