Answer:
B- 70 degrees.
Explanation:
So basically you need to add... 60+50+x=180
You then add 60 plus 50. 110+x=180
Next, you want to subtract 110. -110 -110
Then you should get 70. x=70 degrees
X and Y are vertical angles which means they are always the same degree. So if X is 70 that also means Y is 70!
I hope this helped you!!!
