i think there might be something wrong with the question.
in an inscribed triangle, if one side is the diameter and the opposite vertex is on the circle, that vertex should have an angle of 90. that would make the other two sides 45 degrees since the sides are isoceles.
yet in statement 1, it says that ADE is 50. i realise the figure might not be too scale, but is the assumption that the vertices of the triangle lie on the circle???

Hi all
O is the center (given) and CO therefor is the circle radii R = 6 - statement (1).
The arc BC is 2 pi long (given) - statement (2).
circumference of the circle is 2Rpi = 12pi
the ratio of BC / circumference is 2 / 12
2 / 12 * 360 = 60
we can now tell that BOC = 60 degrees
so my answer is (C)
I didn't gave any weight to AD = AE - is that correct ?
