Height and DistanceHard
Question
AB 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 C on the ground is 60o. He moves away from the pole along the line BC to a point D such that CD = 7 m. From D the angle of elevation of the points A is 45o. Then the height of the pole is
Options
A.
(√3 + 1) m
(√3 + 1) mB.(√3 − 1) m
(√3 − 1) mC.
D.
