Answer:
x = 7
z = 119
Explanation:
Because of vertical angles 8x + 5 = 61
8x + 5 = 61
* subtract 5 from each side *
5 - 5 cancels out
61 - 5 = 56
8x = 56
* divide each side by 8 *
8x / 8 = x
56 / 8 = 7
x = 7
Because of supplementary angles z + 61 = 180
z + 61 = 180
* subtract 61 from each side *
61 - 61 cancels out
180 - 61 = 119
z = 119
