Answer:
x ≥ 4; solid circle at 4 and shaded to the right
Step-by-step explanation:
Given:
x +2 ≥ 6
Subtract 2
x +2 -2 ≥ 6 -2
x ≥ 4
This is graphed as a solid circle at x=4 and shaded to the right (where x > 4).
sum of an exterior angle is 360
2x+56+85+57+4x=360
6x+198=360
6x=360-198
6x=162
x=162/6
x=27
