5. List the sides of triangle DEF in order from shortest to longest if m<D = 20, m<E = 120, and m<F = 40

thanks for 30 points bae

Step-by-step explanation:

honestly bro aint no one got time to answer these dumb question just do it p***y

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.
