Answer: ↴
Length of Segment XY =>9 cm
Now We have to check options
YZ=>9 cm ( It can be true if XYZ is assumed to be isosceles triangle)
XZ=> 9 cm ( Same It also can be true if XYZ is assumed to be isosceles triangle)
XZ=>973 cm or 9.73 cm ( not clearly specified in question) But it is possible as Two sides can be taken of any length )
XZ= 2XY Again It is also possible
YZ is longest side In triangle There should be longest side if it is not equilateral.
So , XZ= 2XY and YZ is longest side are more accurately possibilities of triangle XYZ
