Answer:
x = 17
Explanation:
1. First, we should know that all angles in any triangle add up to 180°.
- This means that x + 17 + 6x + 10 + 4x - 34 = 180
2. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Add 7 to both sides.
Step 3: Divide both sides by 11.
Step 4: Check if solution is correct.
Therefore, x = 17.
