57 + x + x + 130 = 167
57 + 2x + 130 = 167
187 + 2x = 167
- 187 - 187
---------------------------
2x = -20
------ -------
2 2
x = -10
On the X side it’s +1
Hopefully this helps
1/6 for the first question and 1/3 for the second
Your answer would be R=-5x-4+y
They are alternate Exteror angles and internet but as for the question they would be corresponding angles
