Question 1
The distance between two pillars of length 16 metres and 9 metres is x metres. If two angles of elevation of their respective top from the bottom of the other are complementary to each other, then the value of x (in metres) is
Question 2
The length of the shadow of a vertical tower on level ground increases by 10 meters when the altitude of the sun changes from 45 ° to 30 °. Then the height of the tower is
Question 3
A man standing at a point C is watching the top of a tower, which makes an angle of elevation of 30 °. The man walks some distance towards the tower and then his angle of elevation of the top of the tower is 60 °. If the height of the tower is 30 m, then the distance he moves is
Question 4
If a pole of 12 m height casts a shadow of 
m long on the ground, then the sun’s angle of elevation at that instant is
m long on the ground, then the sun’s angle of elevation at that instant is Question 5
From two points on the ground and lying on a straight line through the foot of a pillar, the two angles of elevation of the top of the pillar are complementary to each other. If the distances of the two points from the foot of the pillar are 12 meters and 27 meters and the two points lie on the same side of the pillar, then the height (in meters) of the pillar is
Question 6
The shadow of a tower standing on a level plane is found to be 40 m longer when the sun's altitude is 45°, than when it is 60°. The height of the tower is:
Question 7
