Answer:
Step-by-step explanation:
Because lines [tex]m[/tex] and [tex]n[/tex] are parallel, angles 1, 3, 4, 6 are equivalent, and all remaining angles are also equivalent.
Knowing this, you can set up the following equation:
[tex]86 = 2x + 25[/tex]
[tex]86 - 25 = 2x[/tex]
[tex]61 = 2x[/tex]
[tex]x = 30.5[/tex]
