QUESTION IS SAYiNG THAT
LINE AB AND CD INTERSECT AT O .
IF <AOC +<BOE=70° AND <BOD =40°FIND <BOE AND REFLEX < COE
1=GIVEN FROM QUESTION =
<AOC+<BOE=70°
And <BOD=40°
as we know =<AOC+<BOE+<COE=180°
because of linear pair equations ..
as we know <AOC +<BOE=70 and
we don't know the < COE..???????
so
<AOC+<BOE+<COE=180°
70°+<COE=180°
<COE=180-70
☆☆☆☆☆☆The angle of COE=110°
2=AND NOW WE HAVE TO FIND THE REFLEX OF <COE
☆THE TOTAL SUM OF REFLEX ANGLE IS =360°
☆then simply we have to subtract <COE frm 360°
☆ =360°-110°=== 250°
NOW WE COME TO KNOW THE REFLEX ANGLE OF <COE=250°
3=NOW at last we have to find the angle of <BOE
then we know that =
☆ CD=COE+BOE+BOD=180°
<BOE+110°+40°=180°
because linear pair equations
than
<BOE+150°=180°
<BOE=30°
☆☆☆☆☆NOW WE COME TO KNOW
THE ANGLE <BOE=30°
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
