Eliana takes a 36-inch by 27-inch rectangle of fabric and cuts from one corner of the piece of fabric to the diagonally opposite corner. Now Eliana has two equally sized triangles of fabric.
What is the perimeter of each triangle?
inches

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

step-by-step explanation:

1

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.
