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 64^o and 62^o respectively. Find the length of the flagstaff.

• A.60 (tan 62^o - tan 64^o)
• B.60 (cot 64^o - cot 62^o)
• C.60 (cot 62^o - cot 64^o)
• D.60 (tan 64^o - tan 62^o)
• E.
