Answer:
x = 3.5 and y = 2
Step-by-step explanation:
The lines of symmetry go through the midpoints of opposite parallel sides. The midpoint of the horizontal sides is at x = (5+2)/2 = 3.5. The midpoint of the vertical sides is at y = (6 -2)/2 = 2.
___
The lines x=2 and y=6 are each at one edge of the figure, so will not be lines of symmetry.
