we know that
If the ΔABC and ΔXYZ are similar. then the corresponding sides of the triangles are proportional
\(\frac{AB}{XY}= \frac{BC}{YZ}= \frac{AC}{XZ}\)
we have
\(AC=15\ units\\XZ=10\ units\)
Find the ratio
\(\frac{AC}{XZ}\)
substitute the values
\(\frac{15}{10}\)
Simplify Divide by \(5\) both numerator and denominator
\(\frac{15}{10}=\frac{3}{2}\)
therefore
the answer is
\(\frac{3}{2}\)
