Answer:
x=13
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
5x = 6x-13
Subtract 6x from each side
5x-6x = 6x-13-6x
-x = -13
Multiply each side by -1
Opposite angles are same
[tex]\\ \sf\longmapsto 5x=6x-13[/tex]
[tex]\\ \sf\longmapsto 6x-5x=13[/tex]
[tex]\\ \sf\longmapsto (6-5)x=13[/tex]
[tex]\\ \sf\longmapsto x=13[/tex]
