Answer:
m∠S=116º
Step-by-step explanation:
What we know)
∠V=64º
Opposite interior angles in a parrelogram are the same
The sum of the interior angles of a quadrilateral is 360º
What we can figure out)
∠T is opposite ∠V
So, ∠T=∠V=64
360º-64º-64º=∠S+∠U
232º=∠S+∠U
∠S is opposite ∠U
So, ∠S=∠U=232/2
232/2=116
∠S=116º
