Answer:
Angle COD is 20° and angle BOE is 155°.
Think of the line is the middle of a circle and each half of the circle equals 180° and the whole circle equals 360°. Now to find <COD you must take the measure of <AOD and subtract that from 180 which will give you <COD. To find <BOE you think of it as a whole circle. You must add <DOE to <COD and <BOC. After finding this sum you must subtract this from 360 giving you <BOE.
