A flagstaff stands on the top of a vertical tower. A man standing 60 m away from the tower observes that the angles of elevation of the top and bottom of the flagstaff are 64o and 62o respectively. Find the length of the flagstaff.

60 (tan 62^o - tan 64^o)

60 (cot 64^o - cot 62^o)

60 (cot 62^o - cot 64^o)

60 (tan 64^o - tan 62^o)

Correct answer is D

\(\frac{BC}{60}\) = \(\frac{tan 62}{1}\)

BC = 60 tan 62

\(\frac{AC}{60}\) = \(\frac{tan 62}{1}\)

AC = 60 tan 64

AB = AC - BC

= 60(tan 64^o - tan 62^o)
