degrees

Therefore,   [vertically opp angles]

Given that,

Therefore,

I am not sure, from where did "E" comes?
e bisects angle COB
Your question is like this:- (1).AB and CD intersect at O. (2).Angle BOC is bisected by OE. (3). Angle AOC + Angle EOC = 70. (4). Angle BOD = 40. (5). Find angle BOE . (6). Find reflex angle COE. Answer:- (5). As OE bisects angle BOC, hence angle BOE = angle COE = 70. (6). (i) Angle AOD = vertically opposite angle BOC = angle BOE+ angle COE = 70+70 = 140. (ii) Angle COA = vertically opposite angle BOD = 40. Therefore reflex angle COE = 360 - angle COE = 360 - 70 = 290.

What is point E ?
Also check the statement of the question again. There seems to be error with angles AOC and BOC being equal to 70 as AB is a straight line.
E bisects angle COB
