Question

identify all angles that are not adjacent to ∠snu

Explanation:

Step1: Recall adjacent - angle definition

Adjacent angles share a common side and a common vertex.

Step2: Analyze each angle

• $\angle RNV$: Shares vertex $N$ but no common - side with $\angle SNU$, so it is not adjacent.
• $\angle VNT$: Shares vertex $N$ but no common - side with $\angle SNU$, so it is not adjacent.
• $\angle RNT$: Shares vertex $N$ but no common - side with $\angle SNU$, so it is not adjacent.
• $\angle SNR$: Does not have the vertex $N$, so it is not adjacent.
• $\angle TNU$: Shares a common side $NU$ and vertex $N$ with $\angle SNU$, so it is adjacent.

Answer:

$\angle RNV$, $\angle VNT$, $\angle RNT$, $\angle SNR$
