Answer 2

Answer:

OBA=30°and BOC=150°

Step-by-step explanation:

NMO=20°[given]

MOD=NMO=20°(corresponding angles)

MOC+MOD=180°(linear pair )

MOC+20°=180°

MOC=180°_20°

MOC=160°

BOM=310°(given)

MOC+BOC=BOM

160°+BOC=310

BOC=310°_160°

BOC=150°

BOD+BOC=180°(linear pair)

BOD+150°=180°

BOD=180°_150°

BOD=30°
