m<7=69 degrees

Step-by-step explanation:

<7 + <8 = 180 degrees because the measure of a straight line is 180 degrees.

m<8 = 111

m<7= x

111+x=180

x=69

So m<7 = 69 degrees

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
