Answer:
Equation: (5x - 8) + (3x + 12) = 180
x = 22
Explanation:
We can tell that ACB is a straight line and that a straight line is equal to 180 degrees. Using this logic, we will write our equation;
Given:
(5x - 8) + (3x + 12) = 180
Combine like terms:
8x + 4 = 180
Subtract 4 from both sides of the equation:
8x = 176
Divide both sides of the equation by 8:
x = 22
