Answer:

XY = 18

Step-by-step explanation:

The figures are similar so the ratios of corresponding sides are equal, that is

[tex]\frac{XY}{BC}[/tex] = [tex]\frac{YZ}{CD}[/tex] , substitute values

[tex]\frac{XY}{12}[/tex] = [tex]\frac{15}{10}[/tex] ( cross- multiply )

10 XY = 180 ( divide both sides by 10 )

XY = 18
