Pls help and show workings

x = 30

Step-by-step explanation:

Since RQ bisects ∠ PRS, then

∠ SRQ = ∠ PRQ , substitute values

3x - 20 = x + 40 ( subtract x from both sides )

2x - 20 = 40 ( add 20 to both sides )

2x = 60 ( divide both sides by 2 )

x = 30

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
