(4)1m3+1AB is a vertical pole with B at the ground level

and A at the top. A man finds that the angle of

elevation of the point A from a certain point C600.He moves away from the pole along the lineCD- 7m

.From D the angle of elevation of the point Aon the ground isBC to a point D such that.Then the height of the pole is (1)7/3

7/3

7/3

7/3V33+1m
