In colorado, the temperature was 17.2° below zero. if the temperature continues to drop 4° every hour, what is the new temperature after 5.5 hours? explain

-4.8°

Step-by-step explanation:

5.5 x 4

= 22

17.2 - 22

=4.8

17.08

correct me if i am wrong.

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.
