Let's analyze the problem and solve for $x$ and $y$.

The given diagram shows four parallel lines $m \parallel n \parallel p \parallel q$, with two transversals. The angles provided are:

1. $(6x - 76)^\circ$
2. $80^\circ$
3. $y^\circ$

Step 1: Properties of Parallel Lines

• When parallel lines are intersected by a transversal, corresponding angles are equal.
• Alternate interior angles are also equal.

Step 2: Solving for $x$

The angle $(6x - 76)^\circ$ and the $80^\circ$ angle are corresponding angles. Since the lines are parallel, they must be equal: $6x - 76 = 80$

Solving this equation: $6x = 80 + 76$ $6x = 156$ $x = 26$

Step 3: Solving for $y$

The $y^\circ$ angle and $80^\circ$ are alternate interior angles. Thus, $y = 80$.

Final Values:

$x = 26, \quad y = 80$

Here are five related questions for exploration:

1. What are other angle relationships when parallel lines are cut by a transversal?
2. What happens if the transversals are not perpendicular to the parallel lines?
3. How would the solution change if one angle was exterior instead of interior?
4. How are corresponding angles used in real-life constructions?
5. What is the significance of the sum of angles around a point?

Tip: Always identify corresponding, alternate, or supplementary angles in diagrams with parallel lines to simplify calculations.
