The answer to this question is C because all the other answers have a variable which will always have an answer beside it
The size of an exterior angle is equal to the sum of the two remote interior angles. in this example
4x-18=(2x+6)+(36)
4x-18=2x+42
2x=60
x=30. so the exterior angle measures
4(30)-18=102
