Find the value of the variable. then find the measure of each labeled angle

x=20

4x=80

5x=100

Step-by-step explanation:

The other angles equal the marked angles.

All angles =360.

4x+5x +4x+5x= 360

18x=360

X=20

your answer would be b

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
