Question

plz tell answer if this question

Answer 1

1)
m angle AOB is congruent to m angle DOC (vertically opposite angle)
Therefore ,m angle AOB =118 degree (given)
Therefore, m angle BPC = 47 degree
m angle AOB +m angle AOD =180 degree (angle forming a linear pair)
Therefore, m angle AOD +118= 180
Therefore, m angle AOD=180-118
Therefore, m angle AOD=62 degree
Therefore,m angle AOD is congruent to m angle COB (vertically opp angle)
Therefore,m angle AOD =62 degree
Therefore, m angle COB= 62 degree
