To determine if two angles are adjacent, we need to understand the definition of adjacent angles. Two angles are considered adjacent if they have a common vertex (a common endpoint) and a common side (a common ray extending from the vertex).
In this case, we are given three angles: aob, cod, and boc.
To find out if aob and cod are adjacent, we need to check if they have a common vertex. From the given information, we know that aob has vertex o and cod has vertex o. Therefore, aob and cod have a common vertex.
Next, we need to determine if aob and cod have a common side. Since aob is defined by a ray extending from vertex o, and cod is also defined by a ray extending from vertex o, they have a common side.
Based on the definition of adjacent angles, we can conclude that aob and cod are indeed adjacent.
Regarding the third angle, boc, we can determine its adjacency with either aob or cod. As before, we need to check if boc shares a common vertex and a common side with aob or cod.
Since aob and cod have a common vertex o, boc can be adjacent to either of them. However, we don't have any information about the angle measurement of boc, so we cannot determine its adjacency based on the given information.
To find the value of angle boc, we may need additional information or a different angle relationship. Without more data or context, we cannot determine the exact measurement of angle boc.
