Triangle XYZ is formed by the three squares J, K, and L: A right triangle XYZ is shown. On the side XY of this triangle is a square. Inside the square is written Square J, and below it and inside the square is written Area equal to 144 square units. On the side YZ of this triangle is another square. Inside the square is written Square K, and below it and inside the square is written Area equal to 256 square units. On the side XZ of this triangle is another square. Inside the square is written Square L, and below it and inside the square is written Area equal to 400 square units.

Which statement best explains the relationship between the sides of triangle XYZ?

XY + YZ = ZX, because 144 + 256 = 400
(XY)2 + (YZ)2 = (ZX)2, because 144 + 256 = 400
(XY)2 + (YZ)2 = (ZX)2, because 202 + 122 = 162
XY + YZ = ZX, because 202 + 122 = 162
