Answer:
UV = 45
Step-by-step explanation:
From the diagram, Δ WXY and Δ WUV are similar.
Thus the ratios of corresponding sides are equal, that is
[tex]\frac{XY}{UV}[/tex] = [tex]\frac{WX}{WU}[/tex], substitute values
[tex]\frac{20}{UV}[/tex] = [tex]\frac{8}{18}[/tex] ( cross- multiply )
8UV = 360 ( divide both sides by 8 )
UV = 45
