If you plug that into a calculator you get 4.5
180-135= 45 degrees(angles in a straight line add up to 180)
Alternate angles are equal
x+57+45=180( interior angles of triangle add up to 180)
x= 78
Hope this helps.

Step-by-step explanation:
they aren't similar because they have corresponding angles and wouldn't be similar because that is if they are the same side lengths with different angles
