A poster is on top of a builiding. A person is standing on the ground at a distance of 50 m from the building. The angles of elevation to the top of the poster and bottom of the poster are 45° and 30°, respectively. What is 200% of the height (in m) of the poster?
1
\(25 \over 3\) \((3 - \sqrt {3}) \)
2
\(75 \over 3\)\((3 - \sqrt {3})\)
3
\(50 \over 3\)\((3 - \sqrt {3})\)
4
\(100 \over 3\)\((3 - \sqrt {3})\)
