An illustration shows five rays with points near the arrows labeled A, B, C, D, and E in a counterclockwise direction, emerging from a common point labeled O. The points A, O, and E fall on a straight line. All the four angles are marked but unlabeled.
Which angle(s) are adjacent to ∠DOC?
(1 point)
Responses
∠AOD
∠EOD and ∠COB
∠AOB and ∠EOA
∠DOB
The angle(s) that are adjacent to ∠DOC are: ∠AOD and ∠AOB
only the answers
∠AOD and ∠AOB
that is not an answer choice
Apologies for the confusion. The correct answer choice is:
∠EOD and ∠COB
