Each quadrilateral below is a parallelogram. Find the missing measures

earnstyle [38]

Answer:

$ST=3$ , $VT=10$ , $m$ ∠ $V=48$ °, $m$ ∠ $T=132$ °

Step-by-step explanation:

In a parallelogram, opposite sides are congruent and therefore have the same length. Thus, $ST=RV=3$ and $VT=RS=10$ .

Similarly, opposite angles in a parallelogram are congruent and therefore have the same measure. Thus, $m$ ∠ $V=m$ ∠ $S=48$ ° and $m$ ∠ $T=m$ ∠ $R=132$ °. Hope this helps!
