Solution

  • Given that,
Angle AOC+ Angle BOC+ Angle BOD=338°
  • We know that
Sum of all angles is 360
  • Angle AOC+ Angle BOC+ Angle BOD + Angle AOD = 360
  • 338 + angle AOD = 360 ( Acc. to Question)
  • Angle AOD = 360-338 =22
  • Angle AOD = angle BOC (Because they are vertically opposite angles)
They are equal to 22
  • And
  • Angle BOC + angle BOD = 180 ( Because linear pair...sum of those angles will be 180)
  • 22+angle BOD = 180
  • Angle BOD = 180-22
  • Angle BOD = 158
  • Angle BOD = Angle AOC = 158 (Because vertically opposite angles are equal)

Angle AOC = 158
Angle BOC = 22
Angle AOD = 22
Angle BOD = 158
