Answer:
(C)only line u and line v
Step-by-step explanation:
To verify this, the easiest route is using corresponding angles.
See the attached image for the missing angles which we use for the comparison.
The angle at t which is supposed to correspond to 89 degrees on s is 91 degrees. <u>Therefore Line t is not parallel.</u>
Line u and v is parallel because the angle at u corresponds to the angle at t.
<u>Therefore, the correct option is C.</u>
