PLEASE HELP MAJOR HELP DUE AT 12AM What happened to get to each step in solving the equation? 1x + x = 180 - 2 Step 1: = 180 – 2 Step 2: * = 180 Step 3: 3 = 72

What is the next step in the given proof? choose the most logical approach. a. statement: m 1 + m 2 + 2(m 3) = 180° reason: angle addition b. statement: m 1 + m 3 = m 2 + m 3 reason: transitive property of equality c. statement: m 1 = m 2 reason: subtraction property of equality d. statement: m 1 + m 2 = m 2 + m 3 reason: substitution property of equality e. statement: 2(m 1) = m 2 + m 3 reason: substitution property of equality
