The point (4, 12) is an ordered pair in a proportional relationship. What equation represents this relationship? 1. y = 3x
2.y = 12x
3.y = 4x
4.y = 48x

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.

yes the data was not prsented

step-by-step explanation:

the answer is 3/2 and for decimal: 1.5
