Answer 1

First, you can notice that the angle of 130 degrees and the angle next to it make up a line. So, they should add up to 180 degrees. We do 180-130 to get 50. So that angle next to 130 is 50 degrees. The interior angles of a triangle should add up to 180 degrees so let’s do 180-50 to get 130. The angles are equal to each other so we can just do 130/2 and get 65 degrees. Lastly, y=65 degrees.
