Hi there!

In order to find x, we'll need to create an expression. We know that angle x would be 180 - angle ABC - y. Since we know that angle ABC is equal to 30, we can substitute that in. This gives us 180 - 30 - y. Lastly, we can simplify to get our expression. The expression is 150 - y. The answer is the first option.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
