Which of the following statements is TRUE based on the information given?
A
If Z1 = 45° then 22 + x3 = 90°
B
If Z2 = 70° then 21+ 23 = 110°
С
If 23 = 55° then 24+ 25 = 125°
D
If 24 = 60° then 21+ 23 = 120°

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
