Step 1: m∠x + m∠y + m∠z = 90 degrees (sum of adjacent angles) Step 2: m∠w + m∠z = 180 degrees (supplementary angles) Step 3: Therefore, m∠x + m∠y + m∠z = m∠w + m∠z Step 4: So, m∠x + m∠y = m∠w In which step did the student first make a mistake and how can it be corrected? Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (sum of angles of a triangle) Step 1; it should be m∠x + m∠y + m∠z = 180 degrees (corresponding angles) Step 2; it should be m∠w + m∠z = 90 degrees (supplementary angles) Step 2; it should be m∠w + m∠z = 90 degrees (adjacent angles)
