ABC is a field in the form of an equilateral triangle. Two vertical poles of heights 45 m and 20 m
are erected at A and B respectively. The angles of elevation of the tops of the two poles from C are
complementary to each other. There is a point D on AB such that from it, the angles of elevation of
the tops of the two poles are equal. Then AD is equal to :
