Answer:

  • x = 2
  • z = 89

Step-by-step explanation:

The angle marked z and the one marked 91° are a "linear pair", so are supplementary.

  z° = 180° -91° = 89°

__

The angle marked (13x +65)° and the one marked 91° are "vertical" angles, so are congruent.

  13x +65 = 91

  13x = 26 . . . . . . . subtract 65

  x = 2 . . . . . . . . . . divide by 13

The variable values are ...

  • x = 2
  • z = 89
