It can also be written as ∠AOC + ∠AOD = 180o By substituting the values 50o + ∠AOD = 180o ∠AOD = 180o – 50o By subtraction ∠AOD = 130o According to the figure we know that ∠AOD and ∠BOC are vertically opposite angles So we get ∠AOD = ∠BOC = 130o According to the figure we know that ∠AOC and ∠BOD are vertically opposite angles So we get ∠AOC = ∠BOD = 50
