Answer:
x = 7
Step-by-step explanation:
The 2 angles are adjacent and sum to 180° , that is
11x + 8 + 12x + 11 = 180
23x + 19 = 180 ( subtract 19 from both sides )
23x = 161 ( divide both sides by 23 )
x = 7
In word form it would be seventy six percent and as a fraction it would be 76/100 or 76

C1 + C2 = 50
6 + C2 = C1
6 + C2 + C2 = 50
6 + 2C2 = 50
2C2 = 44
C2 = 22
C1 = 22 + 6
C1 = 28
