Please answer question

sweet-ann [11.9K]

Given;

ABCDE is similar to VWXYZ

so, the corresponding segments are proportional

We need to find the length of XY

XY is corresponding to CD

CD = 1.2 cm

Finding another two corresponding sides

DE = 3.2 cm , YZ = 4 cm

so,

$\begin{gathered} \frac{XY}{CD}=\frac{YZ}{DE} \\ \\ \frac{XY}{1.2}=\frac{4}{3.2} \\ \\ XY=\frac{4}{3.2}\cdot1.2=1.5\operatorname{cm} \end{gathered}$

So, the length of XY = 1.5 cm
