Question

answer the following question​

Answer 1

Answer:

Angle BOC + Angle AOD = 280

We know that vertically opposite angles are equal ,

angle BOC+angle AOD = 280

2( Angle BOC) =280

Angle BOC = 140

angle BOC + angle AOC = 180 ( by liner pair)

140 + angle AOC =180

angle AOC =180 -140

Angle AOC = 40

Angle AOC = Angle BOD=40

(by vertically opposite angle)

angle AOC=40

Angle COB=140

angle BOD=40

angle COB = 140

angle AOD = 40
