What is a half-angle identity to find the exact value of sin? Group of answer choices

sin⁡θ=(2-cos⁡2θ)/3

sin⁡θ=(1-cos⁡2θ)/2

sin⁡θ=(1+cos⁡2θ)/2

sin⁡θ=(1-cos⁡2θ)/4

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
