3x + 20 and 5x - 80 adds up to 180 3x + 20 + 5x - 80 = 180 8x - 60 = 180 8x = 240 X = 30 5x - 80 + y = 180 5(30) - 80 + y = 180 70 + y = 180 Y = 110

since dey paraoell those 2 angles add to 180 3x+20+5x-80=180 8x-60=180 8x=240 x=30 alright, so since y and 5x-80 are adding to 180 as well, 3x+20=y 3x+20=y 3(30)+20=y 90+20=y 110=y y=110 degrees geo oroperties is that one about paralell lines and oposite angles are supplementary and straight lines are 180 degrees
