X=60degrees
bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.
Hope this helps.
The x values are the domain and they y values are the range. So the domain is {-2, 0, 2}. And the range is {-1, 0, 1}. So B is the answer.
(yX3)+1 because product means multipy
