Answer: z = 107; x = 5
Step-by-step explanation:
z = 107 They are vertically opposite angles, which they are equal.
z + (6x + 43) = 180
1. Plug in 107 for z.
107 + (6x + 43) = 180
2. Get rid of parentheses.
107 + 6x + 43 = 180
3. Sum up the number in the left sides.
6x + 150 = 180
4. Subtract 150 from both sides.
6x = 30
5. Divided 6 from both sides.
x = 5
