From the top of a building of height $$h,$$ the angle of depression of an object on the ground is $$\theta.$$ What is the distance of the object from the foot of the building in terms of $$h$$ and $$\theta?$$

The angle of elevation of a tower at a level ground is $$30^o$$ . The angle of elevation becomes $$\theta$$ when moved 10 m towards the tower. If the height of tower is $$ 5 \sqrt{3} m $$, then what is $$\theta$$ equal to ?

Two poles are 10 m and 20 m high. The line joining their tips makes an angle of $$15^o$$ with the horizontal. What is the  distance between the poles ?

From an aeroplane above a straight road the angles of depression of two positions at a distance 20 m apart on the road are observed to be $$30^o$$ and $$45^o$$. The height of the aeroplane above the ground is :  

The angle of elevation of the top of a tower standing on a horizontal plane from two points on a line passing through the foot of the tower at distances $$49\ m$$ and $$36\ m$$ are $$43^{\circ}$$ and $$47^{\circ}$$ respectively. What is the height of the tower?
