To determine which angle(s) are adjacent to ∠DOC, we need to consider the definition of adjacent angles. Two angles are adjacent if they share a common vertex and a common side, but do not overlap.

In this case:

  • ∠DOC has the rays OD and OC.
  • The angles adjacent to ∠DOC would be the angles that share ray OC and ray OD.

Based on the configuration:

  1. ∠EOD uses ray OD and a ray leading towards point E, making it adjacent to ∠DOC.
  2. ∠COB uses ray OC and a ray leading towards point B, making it adjacent to ∠DOC.

Thus, the angles that are adjacent to ∠DOC are:

∠EOD and ∠COB (angle EOD and angle COB).
