Answer 2

Answer:

In the given figure AE is // to OD,

and OC is the transversal 40°+angle EDO=180°( since,sum of two interior angles of same side of tranversal is 180°)

So,angle EDO = 180°-40°=140°

Now take the transversal as EB ,then

140°+angle CDE= 180°(since,sum of two interior angles of same side of the transversal is180°)

Therefore,angle CED=180-140=40°......
