What times 1,000 equals 4,320

4.32

Step-by-step explanation:

Call the unknown number = x

We have: 1000x = 4320

=> x = = 4.32

=> The number we need to find is 4.32

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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.
