Answer:
B. 26.65
Step-by-step explanation:
QRST is a parallelogram
so
QR = TS = 7
and
QT = RS = √[(6)^2 +(2)^2] = √40 = 6.3246
So the perimeter of parallelogram:
= 2(7) + 2(6.3246)
= 14 + 12.6492
= 26.65
Answer is B. 26.65

Answer:
x = 70
Step-by-step explanation:
Properties of a parallelogram.
1). Pair of opposite sides of a parallelogram are equal in measure and parallel to each other.
2). Opposite angles of a parallelogram are equal in measure.
3).Adjacent angles of a parallelogram are supplementary.
By the second property,
(2x - 30) = (x + 40)
2x - x = 30 + 40
x = 70
