**Figure Description:**
The image displays two parallel lines, labeled 'r' and 't', intersected by a transversal line segment.
Line r is on the left and line t is on the right. Both lines are oriented diagonally, sloping upwards from left to right.
The transversal connects line r to line t, sloping downwards from left to right.
Three angles are labeled with expressions:
1. At the intersection of line r and the transversal:
* An angle above the transversal and to the right of line r (an interior angle) is labeled (5y - 9)°.
* An angle below the transversal and to the right of line r (an interior angle) is labeled (5x + 4)°.
These two angles, (5y - 9)° and (5x + 4)°, are adjacent angles on the straight line r, meaning they are supplementary.
2. At the intersection of line t and the transversal:
* An angle below the transversal and to the left of line t (an interior angle) is labeled 3x°.
The problem states that line r is parallel to line t (r || t).
The angles (5x + 4)° and 3x° are consecutive interior angles (or same-side interior angles), which are supplementary when lines are parallel.
Alternatively, the angle (5y - 9)° and the angle 3x° are alternate interior angles, which are equal when lines are parallel.
