I figured out most of the angles and know how to complete it, just not with the options it gives me in the dropdown menu :/ given:
- ab || cd , ad || bc , de ⊥ fc

the options:
- vertical angles
- linear pair (or triple)
- congruent angles
- sum of angles in a triangle
- sum of angles in a quadrilateral
- base angle of an isosceles triangle
- angle bisector definition
- corresponding angles
- alternate interior angles
- alternate exterior angles
- same side interior angles
- angle addition posulate
- angle subtraction postulate
- perpendicular lines form right angles

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?

have a splendid day < 3 : )

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

it has to have an angle of 90 degrees
