Answer 2

Step-by-step explanation:

 We know that, angle x+y+z+w= 360 degree,

since x+y=z+w, we can replace z+w with x+y in the above equation,

 hence, x+y+x+y=360

               2x+2y=360,

               2(x+y)=360,    (taking 2 commonly outside).

                  x+y=360/2,

                   x+y=180 degree.

Therefore AOB is a line as angles x and y make a straight angle 180 degree.
