Answer:
122°
Step-by-step explanation:
The formula for finding the sum of all angles in a polygon is:
(n-2) * 180°
n is the number of angles
Here n = 7, so the sum of all angles is
(7-2) * 180° = 900°
x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°

Answer:
(6r+7)+(13+7r)=13r+20
(13-1/2r)-(1-r)=12-1/2r
(-8-r)+(2r-4)=-12+r
Last one is r-13/6
