Let a quadrilateral ABCD be inscribed in a circle such that AB=5, BC=3, CD=2 and Angle B=60 degrees.
Find length AC
Find length DA
Okay, i found AC but i can't seem to find DA. I know im suppose to relate the 60 degrees to some other triangle but I just can't seem to find any relation. Am I missing a postulate about internal angles of a quadrilateral inscribed in a circle? XD
