begin mathsize 16px style To space find colon space the space reflex space angle BOC Given space that space angle BAC equals 65 degree We space know space that space angle space subtended space at space the space centre space by space an space arc space is space double space the space angle subtended space at space any space point space on space the space circle space by space the space same space arc. So comma space angle BOC equals 2 angle BAC equals 2 cross times 65 equals 130 degree But space we space want space the space reflex space angle space BOC. So comma space the space reflex space angle BOC equals 360 degree minus 130 degree equals 230 degree end style
