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:

• $x = 32^\circ$
• $y = 128^\circ$
