John has yellow green and red cubes each with the sideline see a yellow cubes are glued together to make a larger q and even larger cube is made by gluing on green cubes until no yellow cubes can be seen after that john covers the green cubes with the red ones so that green can also cannot be seen making an even larger cube the minimum number of green and red cubes were used to cover previous colors what is the volume of the final big red cube

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.
