Question

wxyz ~ qtsr. find rs.
rs = \boxed{}
save answer

Explanation:

Step1: Identify similarity ratio

The ratio of corresponding sides of similar polygons is equal. For WXYZ ~ QTSR, side WZ (length 3) corresponds to side QR (length 1). The scale factor from WXYZ to QTSR is $\frac{1}{3}$.

Step2: Match corresponding sides

Side XY (length 3) in WXYZ corresponds to side RS in QTSR. Use the scale factor to find RS:
$RS = 3 \times \frac{1}{3}$
