ABCD is not drawn to scale. Based on the angle measures given, ABCD a parallelogram.

A. must not be
B. may or may not be
C. must be

The quadrilateral ABCD must be a parallelogram.

For a parallelogram, the opposite angles and sides are always equal.

From the given quadrilateral, you can see that opposite angles are equal that is:

Based on this, we can conclude that the quadrilateral ABCD must be

step-by-step explanation:

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
