Answer:
<Q = 30
Step-by-step explanation:
2x + 70 + x - 10 = 180
3x + 60 = 180
3x = 120
x = 40
x - 10
40 - 10
30
<Q = 30 because of vertical angles
Solve the parenthesis firt.
17-9 = 8
3*2 = 6 now multiply 6 by 8 that equals 48
now divide 48 by 2
48÷2= 24
It would be 80 because 2 times 120 is 240. 240 divided by 3 is 80

57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20
