Lines x and y are parallel but the figure is not drawn to scale.

Line x: (4y+18)°
Line y: (x+24)°

Since lines x and y are parallel, their corresponding angles are congruent. Therefore, we can set the expressions for the angles equal to each other and solve for x:

4y + 18 = x + 24

Subtracting 18 from both sides, we get:

4y = x + 6

Subtracting x from both sides, we have:

4y - x = 6

Therefore, the equation for line y is 4y - x = 6.

To determine the relationship between lines x and y, we can use the fact that parallel lines have the same slope.

1. Start with line x: (4y+18)°.
2. This equation represents the measure of an angle on line x.
3. Similarly, line y has an angle measure represented by (x+24)°.
4. Since lines x and y are parallel, the angle measures must be equal.
5. Set (4y+18)° equal to (x+24)°: 4y+18 = x+24.
6. Solve for y: 4y = x+24-18.
7. Simplify: 4y = x+6.
8. Divide both sides by 4 to solve for y: y = (1/4)x + (6/4).
9. The equation obtained, y = (1/4)x + (6/4), represents the relationship between lines x and y, given that they are parallel.

Note: The equation y = (1/4)x + (6/4) represents the slope of line y, which is 1/4, and the y-intercept, which is 6/4 or 1.5.

To determine the relationship between the angles formed by parallel lines, we need to use a property called corresponding angles.

Corresponding angles are formed when a transversal (a line that intersects two or more other lines) intersects a pair of parallel lines. These angles are located in matching positions relative to the two parallel lines. In other words, they are in the same position on each of the two lines.

In this case, we have line x and line y, which are parallel. We also have two angles, (4y+18)° on line x and (x+24)° on line y. Since the lines are parallel, we can say that these two angles are corresponding angles.

To prove that the two angles are congruent or equal, we need to equate the expressions for the angles and solve for the variable.

Set (4y+18)° = (x+24)° and solve for x.

4y + 18 = x + 24

To isolate x, subtract 24 from both sides of the equation:

4y - 6 = x

So, the value of x is 4y - 6.

Now you can substitute this value back into either of the angle expressions to find the measure of the angles.

For example, if we substitute x = 4y - 6 into the expression for angle on line y, we get:

(x+24)° = (4y-6+24)° = (4y+18)°

Thus, we have proven that angle (4y+18)° on line x and angle (x+24)° on line y are congruent corresponding angles given that lines x and y are parallel.
