Answer: Every answer choice is to be selected
Explanation:
The following angles are adjacent to angle 8
Adjacent angles share a common line segment, line, or ray. Think of it like a shared wall. The other remaining angles are non-adjacent even though something like angle 6 shares a common vertex with angle 8, they don't share a common wall. In a sense, the person living in apartment 6 isn't a direct next door neighbor to the person in apartment 8.
So that's why we select angles 2, 4, 5, 1 and 3 as our answers. In short, we click each box to select all answer options.
