Answer:
x = -8
Step-by-step explanation:
1. Because the line the angles x + 96 and 100 + x are on is straight, it's a straight angle that results in 180°.
2. Given the above information, that means x + 96 + 100 + x = 180.
3. (Solving for equation above)
Step 1: Simplify both sides of the equation.
Step 2: Subtract 196 from both sides.
Step 3: Divide both sides by 2.
Step 4: Check if solution is correct.
Therefore, x = -8.
