Geometry extra points what is the conclusion of the following conditional? a number is divisible by 2 if the number is even. select one: a. the sum of the digits of the number is divisible by 2. b. if a number is even, then the number is divisible by 2. c. the number is even. d. the number is divisible by 2.

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
