6. A man standing at a point P is watching the top of a tower, which makes an angle of elevation of 30″
with the man’s eye. The man walks some distance towards the tower to watch its top and the angle of
elevation becomes 60°. What is the distance between the base of the tower and the point P?

 
 
 
 

7. The angle of elevation of the top of a tower from a certain point is 30°. If the observer moves 20 m
towards the tower, the angle of elevation of the top of the tower increases by 15. The height of the
tower is:

 
 
 
 

8. A man is watching from the top of a tower a boat speeding away from the tower. The boat makes an
angle of depression of 45° with the man’s eye when at a distance of 60 meters from the tower. After 5
seconds, the angle of depression becomes 30. What is the approximate speed of the boat, assuming
that it is running in still water?
