The diagram shows a set of parallel lines cut by a transversal, forming angles that can be solved using angle relationships. Let’s analyze and solve for $x$ and $y$.

Step 1: Identify Angle Relationships

From the diagram:

• The angle labeled $(8x + 5)^\circ$ is corresponding to the angle labeled $(10x - 27)^\circ$. Corresponding angles are equal.
• The angle labeled $(2y + 9)^\circ$ and the angle labeled $(10x - 27)^\circ$ are consecutive interior angles, meaning they are supplementary (sum to $180^\circ$).

Step 2: Solve for $x$

Since corresponding angles are equal: $8x + 5 = 10x - 27$ Solve for $x$:

1. Subtract $8x$ from both sides: $5 = 2x - 27$
2. Add 27 to both sides: $32 = 2x$
3. Divide by 2: $x = 16$

Step 3: Solve for $y$

Using the supplementary angle rule: $(2y + 9) + (10x - 27) = 180$ Substituting $x = 16$:

$(2y + 9) + (10(16) - 27) = 180$

$2y + 9 + 160 - 27 = 180$

$2y + 142 = 180$

Subtract 142 from both sides:

$2y = 38$

Divide by 2:

$y = 19$

Final Answer:

$x = 16, \quad y = 19$
