What would the answer for X be ??

  140°

Step-by-step explanation:

The external angle is half the difference between the intercepted arcs. One arc is shown as 30°. The other will be the difference between 180° and (30°+x). Then we have ...

  (30 -(180 -(30+x)))/2 = 10

  x -120 = 20 . . . . . . . multiply by 2 and simplify

  x = 140 . . . . . . . . . . . add 120

The measure of arc X is 140°.

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
