2x + x + 67+89 =369 degree ( sum of all exterior angles of polygon is 360)
3x + 126= 360
3 x = 360-126
X = 234/3 = 78
3x + 126= 360
3 x = 360-126
X = 234/3 = 78

it's right answer
Sorry 67 + 89 = 156
3x + 156 = 360
3x = 360-156
X= 204/3 = 68
X= 204/3 = 68
And it is 360 degree not 369
Is it 68 or 78 ??
