Given <1 and <2 are a linear pair, choose the correct reasoning to conclude that m<1+m<2=180 degrees.

• Given <1 and <2 form a linear pair then by the Linear Pair Theorem the two angles are supplementary. If the two angles are supplementary then by the definition of supplementary, the sum of their measures is 180 degrees. Therefore, m<1+m<2 = 180 degrees.
