Question

In figure lines AB and CD intersect at O if angle AOC + BOE =70 degree angle BOD =40 degree find angle BOE and reflex angle COB

Answer 1

Step-by-step explanation:

Aoc + boe = 70 given

bod = 40

aoc = bod =40 (vertically opposite angle)

so

aoc + boe = 70

boe = 70-40=30

aob = 180 ( linear pair)

aoc+ coe+ boe = 180

40 + coe +30 =180

coe=180-70=110

now reflex coe

aoc+ aod+bod+boe=360

aod= coe( vertically opposite angle)

reflex coe= 360

coe= 110

reflex coe = 360-coe

360-110=250
