[tex]y = 65[/tex]

Since it is vertically opposite to that angle, it means that it's equal to it as well.

[tex]x + 65 = 180[/tex]

[tex]x = 180 - 65[/tex]

[tex]x = 115[/tex]

X is supplementary to the angle besides it, meaning that their sum must he 180.

[tex]z = x = 115[/tex]

Vertically opposite as well. :)
