Each of the sails on Joshua’s sailboat forms a triangle. The side lengths of one sail are 13, 17, and 20. What is the measure of each side of the sail?

• XY = 13, XZ = 20, YZ = 17

• XY = 17, XZ = 13, YZ = 20

• XY = 20, XZ = 17, YZ = 13

• XY = 13, XZ = 17, YZ = 20

*the largest angle is opposite the longest side length

• XY = 13, XZ = 20, YZ = 17

• XY = 17, XZ = 13, YZ = 20

• XY = 20, XZ = 17, YZ = 13

• XY = 13, XZ = 17, YZ = 20
