In the figure AB parallel to CD. If angle ABR = 45 degree and angle ROD = 105 degree then find angle ODC Share with your friends Share 7 Mayank Jha answered this Dear student, Let us construct the lines OQ and RP.∠ABO = ∠BPD = 45°In △OPD, ∠OPD + ∠POD + ∠ODP = 180°or, 45° + 105° + ∠ODP = 180°or, ∠ODP = 180° - 45° - 105° = 30°Thus, ∠ODC = 30° Regards 29 View Full Answer Sangeeth Sivadasan answered this ABR=ODC (Alternative interior angles) ODC= 45 -7
