Answer:
y=67
x=113
z=113
Step-by-step explanation:
Because y is a vertical angle to 67, y=67
y and z are supplementary (they equal 180) so z= 113
x and z are vertical so x is also =113
see below
67 and y are vertical angles and vertical angles are equal
y = 67
67 and x are supplementary angles since they form a straight line
67+x = 180
x = 180-67
x = 113
