Answer:

m∠QSR+m∠UVX=180° , Same-side exterior angles theorem

Step-by-step explanation:

The theorem states that same-side exterior angles are supplementary

Answer:

Co - interior angles of a parallelogram add up to 180 degrees

Step-by-step explanation:

Since UW and RT are parallel lines we can infer that if the QSR was flipped and joined to UVX it would create a parallelogram. Angle theorem states that co -interior angles of a parallelogram add up to 180 degrees.
