Answer:
The lines are parallel because they have the same slope(5x)
Applying the properties of a parallelogram, the values of x and y are: x = 8; y = 20.9
<h3>Properties of a Parallelogram</h3>
- The opposite sides in a parallelogram have the same length.
- Opposite angles are equal.
- Adjacent angles in a parallelogram are supplementary.
4x - 17 = 2x - 1 (equal sides)
4x - 2x = 17 - 1
2x = 16
x = 8
(3y+5) + (6y -13) = 180
9y - 8 = 180
9y = 180 + 8
9y = 188
y = 20.9
Therefore, applying the properties of a parallelogram, the values of x and y are: x = 8; y = 20.9
