We need to classify angles 9 and 10.
Step-by-step explanation:
Recall that the two angles are said to be adjacent angles when they share the common vertex and side.
The common vertex of angles 9 and 10 is B.
The common side of angles 9 and 10 is BD.
So angles 9 and 10 share the common vertex B and side BD.
Final answer:
Angles 9 and 10 are adjacent angles.
