Question

AB is a straght line. point O lies on it and point C outside it. if angle AOC is 40° what is the measure of angle BOC?
please do full calculations..​

Answer 1

Answer:

AB is a straight line.

So, Angle AOC + Angle BOC = 180° (linear pair)

40° + Angle BOC = 180°

Angle BOC = 180° - 40°

So, Angle BOC = 140°
