Question

answer the given question​

Answer 1

Answer:

Given

angle BOD = 40 degree

since AB and CD intersect ,

angle AOC = angle BOE ( vertically opposite angle )

Also , angle AOC + angle BOE = 70 degree ( given)

40 degree + angle BOE = 70 degree

angle BOE = 70 degree _ 40 degree

angle BOE = 30 degree

we need to find the reflex angle COE

Reflex angle COE = 360 degree _ angle COE

First we finding angle COE

NOW ,

therefore, angle AOC + angle COE + angle BOE = 180 degree (linear pair )

angle COE +( angle AOC + angle BOE ) = 180 degree

angle COE + ( 40 degree + 30 degree ) = 180 degree

angle COE + ( 70 degree ) = 180 degree

angle COE = 180 degree _ 70 degree

angle COE = 110 degree

Reflex angle COE = 360 degree _ 110 degree

Reflex angle COE = 250 degree
