Question

two lines ab and CD intersect at point O such that angle BOC + angle AOD =280 degree find the value of angle AOC +Angle BOD

Answer 1

Answer:

Step-by-step explanaton:

Given:

Angle BOC+AOD=280

To find :

Angle AOC+BOD?

Solution:

Angle (BOC+AOD)+(AOC+BOD)=360 digree(sum of exterior angle is 360 digree)

280+(AOC+BOD)=360 digree

(AOC+BOD)=360-280

AOC+BOD=80 digree
