Answer:

Step-by-step explanation:

iii) ∠AOE + ∠DOE +  ∠DOB = 180   {Straight line angles}

  67 + ∠DOE + 100 = 180

          ∠DOE = 180 - 167

         ∠DOE = 13°

ii) ∠BOC = ∠AOD    {Vertically opposite angles}

  ∠BOC = ∠AOE + ∠DOE

              = 67 + 13

  ∠BOC = 80°

i) ∠AOC = ∠BOD

∠AOC = 100°
