Answer» m(arc APC) =110°To Find : measure of ANGLE ABCSolution:As figure is missing : CONSIDERING few casesP & B are points in same arc segmentsthen m(arc ABC) = m(arc APC)=> m(arc ABC) = 110°P & B are points in different arc segmentsthen m(arc ABC) + m(arc APC) = 180° ( opposite angles of cyclic quadrilateral ) m(arc ABC) + 110° = 180° => m(arc ABC) = 70°P is at center and B is at remaining circle=> m(arc ABC) = (1/2) m(arc ABPC)=> m(arc ABC) = (1/2)110°=> m(arc ABC) = 55°Learn More:In the adjoining figure, O is the centre of acircle.
