Answer:
WZ = 51 mm.
Step-by-step explanation:
The trapezoid figure STUV is a scaled version of figure WXYZ.
The figure STUV to figure WXYZ has a scale factor of 3 : 1.
So, the corresponding lengths of the two figures will be in the 3 : 1 ratio.
Then, [tex]\frac{ST}{WX} = \frac{TU}{XY} = \frac{UV}{YZ} = \frac{SV}{WZ} = \frac{3}{1}[/tex]
So, SV = 3 × WZ
⇒ 153 = 3 × WZ
⇒ WZ = 51 mm (Answer)
