A quadrilateral in which opposite sides are parallel is called a parallelogram. The correct option is A.
<h3>What is a parallelogram?</h3>
A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
For a parallelogram, the pair of opposite sides are equal and parallel. Therefore,
1.) For the first pair.
(x+8) = 15
x = 7
2.) For the second pair
(x+2)=(2x-5)
x + 2 = 2x - 5
2 + 5 = 2x - x
x = 7
(x+2) = (7+2) = 9
Since the measure of the pair of opposite sides is 15 units, the pair of the other two sides measure 9 units.
Hence, the correct option is A.

Answer:
12 is mean 11 is median range is 14
Step-by-step explanation:
For the Mean
Add all the numbers up
16 + 9 + 20 + 10 =55
12 + 6 + 8 + 15 = 41
55 + 41 = 96
There are 8 numbers so we divide by 8
96/8 = 12
Range is Smallest number minus biggest so 20 - 6 = 14
