Please help: Suppose a line that appears parallel to side BC of △ABC intersects sides AB and AC at points X and Y respectively, and AX/AB=12. How can you determine if the line is or is not parallel to BC? Explain.

step-by-step explanation:

the answer is simply just 6n add the two together as they have an n

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.
