Answer:
The answer is Step 2: m<w + m<z = 180 degrees (suppplmentary angles).
Step-by-step explanation:
First, Step 2 says m<w - m<z = 90 degrees. That's false because the m<w - m<z would equal an acute angle, not a right angle. Secondly, the m<w + m<z = 180 degrees. Supplementary angles equal 180 degrees.
