70

can you tell me how?
anonymous
  • anonymous
why is at 70?
anonymous
  • anonymous
its correct but why?
anonymous
  • anonymous
Because 360-220=140, and the central angle is double the angle in the circumfrence, so its 70

angle BOD =140 centre is O angle subtended by chord on cente is twice the angle subtended on the circle .....so 2x = 140 x = 70
