Order each set of numbers from least to greatest (-2.5, 4, 23, -1, 5, -3, 0.66)

(1, -2.5, 0.75, 3, -0.75)

(63, -34, 36, -27, -13, and 12)

( -3, -2.5, -1, .66, 4, 23 )

( -2.5, -.75, .75, 1, 3 )

( -34, -27, -13, 12, 36, 63 )

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.
