  7-113.
  
  Triangle $ABC$ is similar to triangle $DEF$.
  
  1. Find the scale factor from triangle $ABC$ to triangle $DEF$.
  
  Find the scale factor by using two corresponding sides.
  
  The scale factor is $5$.
  
  2. Find $x$.
  
  Divide by the scale factor.
  
  $x=\frac{38.5}{5}$
  
  3. Find $y$.
  
  Multiply the corresponding side by the scale factor.
