Find the value of x in each case. give reasons to justify your solutions!
b, c ∈ ad

Step-by-step explanation:

DCF is 90°

so to find BCE

BCE+64+90=180

BCE=26°

CBE is (180-3x)

taking triangle BEC

(180-3x)+x+26=180

180-3x+x+26=180

-2x+26=0

-2x=-26

x=13

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

the answer is 8/21

hope this
