Hello, the answer for your question is<span> 12.7.</span>
Answer:
128°
Step-by-step explanation:
x + 154° + 78° = 360° {being complete turn}
x + 232° = 360°
x = 360° - 232°
x = 128°
1.50x = y that should be a good equation hopefully. If it’s wrong I’m so sorry. Also if I were to find the answer I need more of the context of the question
