Find the measure of side XY.

1 answer:

4 0

Answer:

XY = 18

Step-by-step explanation:

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

$\frac{XY}{BC}$ = $\frac{YZ}{CD}$ , substitute values

$\frac{XY}{12}$ = $\frac{15}{10}$ ( cross- multiply )

10 XY = 180 ( divide both sides by 10 )

XY = 18
