as angle doc and cob are linear pair thus the sum of these 2 must be 180
thus doc +125=180
angle doc =55
and by the angle sum property of triangle angle CDO,DOC&DCO will also sum as 180°
thus angle CDO = 180-(70+55)
=55 and as
DC and AB are parallel angle CDO = OAB ( alternate interior angles)
thus angle OAB =55°
hope this might help you
