This could get complicated. Please try to follow my steps carefully:
Begin by writing the equation to be solved: <u>12E - 4 = 0</u>
Add 4 to each side of the equation: 12E = 4
Divide each side by 12: E = 4/12 = 1/3 .
Answer:

Answer:
71°
Step-by-step explanation:
3x° + (x - 11)° + (2x - 55)° = 360°
3x + x - 11 + 2x - 55 = 360°
6x - 66 = 360°
6x = 360° + 66°
6x = 426°
x = 71°
