When you mix two colors of paint in equivalent ratios, the resulting color is always the same. What is the constant of proportionality represented by the following table?

Cups of blue paintCups of yellow paint
15
210
4
20

a
1/5
b
5
c
1/10
d
10

answer for #1 is c

answer for #2 is d

can i get brainliest

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.
