Afarmer needs to enclose a section of land in the shape of a parallelogram by using one side of a barn for one side. the barn and the side opposite of the barn will both be 11 feet long. one of the other sides will be 8 feet long. what is the length of the last side?

8 feet.

Step-by-step explanation:

I drew the  parallelogram in the picture you can see below. With the data of the exercise we realize that the parallelogram is a rectangle. So, with 2 sides of 11 feet long and the other side of 8 feet long, the last side have to measure 8 feet long.

my answer got deleted but it's a

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
