in this picture lines AB and CD are parallel. Find the measures of the following angles. Explain your reasoning.

a. <BCD = 38 degrees, b. <ECF = 38 degrees, c. <DCF = 142 degrees

Step-by-step explanation: <BCD is 38 degrees because if ABC is 38 then BCD is 38. <ECF is also 38 degrees because it is a vertical angle to <BCD and <BCD is 38 degrees. Since there is a straight line it equals 180 degrees. And since <ECF is 38 degrees we subtract 38 from 180 to get 142 degrees. <DCF = 142 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

it is c, trust i got your back lol
