ANSWER
statements accurately describe the triangles
The triangles could not be similar.
The ratios of the side lengths are not consistent.
Reason
As shown in the diagram the sides of the triangle are given
Similarity property on the sides length of the triangle
The corresponding sides of the two triangles are proportional the triangles must be similar.
[tex]\frac{WX}{RT} = \frac{18.0}{8.0}[/tex]
= 2.25
[tex]\frac{WU}{TS} = \frac{15.0}{6.0}[/tex]
=2.5
[tex]\frac{UX}{RS} = \frac{7.5}{3.0}[/tex]
=2.5
Thus by above we get
The ratios of the side lengths are not consistent.
thus triangles could not be similar.
Hence proved
