Geometry quiz! not my strong suit. help please

Assuming PQRS is a parallelogram, we have PQ = RS, and angles S and R are supplementary so their measures sum to 180°.

So

5x = x + 12

4x = 12

x = 3

→   PQ = 5x = 15

and

12z ° + 6z ° = 180°

18z ° = 180°

z = 180/18 = 10

→   m∠S = 12•10° = 120°
