Triangle XYZ is an isosceles right triangle. If side XY is longer than side YZ, and the area of the triangle is 9, what is the measure of side XY?	Choose the correct choice.
A) 4	B) 4√2	C) 8	D) 6	E) Cannot be determined from the information provided
ans D..6..   xy being larger means it is the hyp..   area =(1/2)*(yz)^2=9 or yz=3*\sqrt{2}..   therefore hyp=xy=6
<result>D</result>
