Given parallel lines mm and nn, find the relationship between the angles (6x+5)(6x + 5) and (5x12)(5x - 12) and solve for xx.

STEP 1

Assumptions
1. Lines mm and nn are parallel.
2. The first angle is represented by the expression (6x+5)(6x + 5).
3. The second angle is represented by the expression (5x12)(5x - 12).
4. The relationship between the two angles is not explicitly stated, but since the lines are parallel, we can assume they are either corresponding angles, alternate interior angles, or alternate exterior angles, which are all congruent.

STEP 2

Determine the relationship between the two angles. Since the lines are parallel and the angles are given by algebraic expressions, we can assume that the angles are either corresponding angles, alternate interior angles, or alternate exterior angles. In all these cases, the angles are congruent when the lines are cut by a transversal.
Angle (6x+5)Angle (5x12)\text{Angle } (6x + 5) \cong \text{Angle } (5x - 12)

STEP 3

Set up an equation based on the congruency of the two angles.
6x+5=5x126x + 5 = 5x - 12

STEP 4

Solve for xx by isolating the variable on one side of the equation. Start by subtracting 5x5x from both sides of the equation to get the xx terms on one side.
6x+55x=5x125x6x + 5 - 5x = 5x - 12 - 5x

STEP 5

Simplify the equation by combining like terms.
x+5=12x + 5 = -12

STEP 6

Subtract 5 from both sides of the equation to isolate xx.
x+55=125x + 5 - 5 = -12 - 5

STEP 7

Simplify the equation to find the value of xx.
x=125x = -12 - 5 x=17x = -17
The value of xx is 17-17.
