Solve using substitution –3x + y = –12
5x − 2y = 17
PLZ HELP Will give brainlist to whoever answers first

are you an artist's daughter? cuz dang you a fine piece of art, girl.

i think that you should ask google for the answer to that problem because if we don't know it google does

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.
