Hey there!


x + 19 + 7x + 9 = 180°

1x + 19 + 7x + 9 = 180°

8x + 28 = 180°
SUBTRACT 28 to BOTH SIDES

8x + 28 - 28 = 180° - 28

SIMPLIFY IT!
8x = 180 - 28

8x = 152

DIVIDE 8 to BOTH SIDES

8x/8 = 152/8

SIMPLIFY IT!
x = 152/8

x = 19


Therefore, your answer should be:

x = 19


Good luck on your assignment & enjoy your day!
