Question

which lists all the lines that are parallel to line s? 89° 89° 91° 89° only line v only line t and line v only line u and line v only lines t, u, and v

Explanation:

Step1: Recall parallel - line property

Parallel lines have equal corresponding or alternate - interior angles.

Step2: Check angles

Lines $t$ and $v$ have angles equal to the angle formed by line $s$ and line $r$ ($89^{\circ}$), while line $u$ has a different angle ($91^{\circ}$).

Answer:

only line $t$ and line $v$
