Answer 2

ab and CD intersect at o
Angle AOC+BOE=70 degree
BOD=40degree
to find BOE and COE.
AOD+BOD=180 degree
x. + 40=180
x=180-40
x=140degree
AOC+BOE+COE=180
70+ x=180
x=180-70
x=110 degree
COE=110

AOC=BOD(v.o angle)
AOC=40 degree
AOC+BOE=70degree
40+BOE=70
BOE=70-40=30
boe=30

reflex COE
Aoc+BOE+AOB
70+180=250degree
