Step-by-step explanation:

$\frac{3}{9} = \frac{5}{y} = \frac{x}{12} \\ \frac{3}{9} = \frac{5}{y} \\ 3y = 45 \\ y = 15 \\ \\ \frac{3}{9} = \frac{x}{12} \\ 9x = 36 \\ x = 4$

Are the following angle relationships possible? Explain.

Answer:

Step-by-step explanation:

The 5x+30 is the supplementary angle of the interior one:

180 - 5x - 30 = -5x + 150

Then they have to add up to 180:

4x-9 + 2x+3 -5x + 150 = 180

which simplifies to x = 36

So the angles would be 135, 75 and -30, which is impossible!
