Answer:
X = 10
Z = 67
Explanation:
We see that the angles are formed by the intersection of two lines.
Angles z and 67° are vertically opposite angles and therefore they are equal to each other
z°= 67°
Angles z and (7x + 43) are supplementary angles. The sum of these angles add up to 180°
z + 7x + 43 = 180
67 + 7x + 43 = 180
7x + 110 = 180
7x = 180 -110 = 70
x = 70/7 = 10
