Answer:
x = 13 , z = 74
Explanation:
(14x - 76 )° and 106° are vertically opposite angles and are congruent, so
14x - 76 = 106 ( add 76 to both sides )
14x = 182 ( divide both sides by 14 )
x = 13
-------------------
z° and 106° are a linear pair and sum to 180° , that is
z + 106 = 180 ( subtract 106 from both sides )
z = 74
