Question

which angles are adjacent to each other?

Explanation:

Step1: Recall the definition of adjacent angles

Adjacent angles share a common side and a common vertex, and have no overlapping interior points.

Step2: Analyze each option

• For $\angle8$ and $\angle7$: They share a common vertex and a common side.
• For $\angle1$ and $\angle6$: They do not share a common side or vertex.
• For $\angle6$ and $\angle8$: They do not share a common side.
• For $\angle5$ and $\angle7$: They do not share a common side or vertex.

Answer:

$\angle8$ and $\angle7$
