The image shows a geometric diagram with straight lines \( BG \parallel DE \), and it is labeled with angles and points. The task asks to calculate the values of angles \( x \) and \( y \), with the given angles \( \angle A = 32^\circ \), \( \angle C = 20^\circ \), and \( \angle CBG = 30^\circ \).

### Step-by-Step Solution:

1. **Identify corresponding angles**: Since \( BG \parallel DE \) and \( AF \) is a transversal, \( \angle A = \angle ECF \). Therefore:
   \[
   x = 32^\circ
   \]

2. **Sum of angles in a triangle**: For triangle \( ACF \), we know that the sum of the internal angles of a triangle is \( 180^\circ \). Thus:
   \[
   \angle A + \angle C + \angle y = 180^\circ
   \]
   Substituting the known values:
   \[
   32^\circ + 20^\circ + y = 180^\circ
   \]
   Simplifying:
   \[
   y = 180^\circ - 52^\circ = 128^\circ
   \]

Thus, the values are:
- \( x = 32^\circ \)
- \( y = 128^\circ \)
