Answer:
60 degrees
Step-by-step explanation:
angle y is vertically opposite to angle a, (we can call it.)
angle x is supplementary to the other angle inside the triangle, which we can call angle b.
so, angle a is 60 degrees, as vertically opposite angles are equal
angle b is 60 degrees as supplementary angles = 180
based of the sum of angles in a triangle is 180 theorem;
60+60+unknown= 180
so unknown is 60 degrees
