If x represents the sum of the interior angles of a regular hexagon and y represents the sum of the interior angles of a triangle, then the difference between x and y is equal to the sum of the interior angles of what geometric shape? Choose the most appropriate option:
A) Triangle	B) Square	C) Rhombus	D) Trapezoid	E) Pentagon
Sum of angles of Hexagon = 180*(6-2)=
