are the triangles below acute obtuse or right? ( there’s more but it won’t let me put them on so I’m gonna make multiple questions)

this is obtuse

Step-by-step explanation:

ONE OF THEM IS GREATER THAN 90 DEGREES :)

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
