Question

How do I find angle y?

Answer 1

I think the figure should be like this according to the question that you post previously.

`(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 \\`

The answer should be this. But there's no way to find x according to this figure.
