The problem you provided asks to determine the measure of ∠FBE in the diagram, given that:

• ∠ABF = 75°
• ∠BED = 120°

Step-by-step Solution:

1. Interpretation of the Angles:

   • The points $A, B, C$ appear to be collinear, with lines extending horizontally.
   • The points $G, F, E, D$ form two triangles on top, with $\overline{GF} \parallel \overline{ED}$.
   • $\angle ABF$ and $\angle BED$ are given as $75^\circ$ and $120^\circ$, respectively.

2. Using Parallel Line Theorem: Since $\overline{GF} \parallel \overline{ED}$ and lines $BF$ and $BE$ act as transversals, we can apply the corresponding angle theorem.

3. Calculation of ∠FBE: The sum of the angles at point $B$ must be $180^\circ$, since it's a straight line between $\angle FBE$, $\angle ABF$, and $\angle BED$.

   $\angle FBE = 180^\circ - (\angle ABF + \angle BED)$

   Substituting the known values:

   $\angle FBE = 180^\circ - (75^\circ + 120^\circ)$ $\angle FBE = 180^\circ - 195^\circ = -15^\circ$

   This result seems incorrect, indicating an error in approach. Let me reconsider the relationship between the lines and angles.

Let me reanalyze and correct the approach.
