We know that figure I and figure II are similar, which means that:
-The corresponding angles are equal
-The corresponding sides are at the same ratio.
The ratios between the corresponding sides are:
[tex]\frac{15}{5}=\frac{12}{4}=\frac{8}{2}=\frac{x}{y}[/tex]
You have to compare the determined ratios with the given options to find the true statement.
The only given proportion that is true is the first one
[tex]\frac{x}{y}=\frac{8}{2}[/tex]
