Answer:
I think the figure should be like this according to the question that you post previously.
[tex](8x - 10) + (6x + 12) + y = 180 \\ 8x - 10 + 6x + 12 + y = 180 \\ 14x + y - 2 = 180 \\ 14x + y = 180 - 2 \\ 14x + y = 178 \\ y = 178 - 14x \\ [/tex]
The answer should be this. But there's no way to find x according to this figure.
