PLEASE HELP!! 100 POINTS & BRAINLIEST Write a paragraph proof for the following conjecture:

Given: m<1 + m<2 = m<4

Prove: m<3 + m<1 + m<2 = 180*

Yes, your proof is correct;

However, you should supply the REASONS

angle 2 + angle 3 + angle 4 = 180 < GIVEN

angle 1 + angle 2 = 180 <--- given

angle 1 + angle 2 = angle 2 + angle 3 + angle 4  <--- substitution/ transitive

angle1 + angle 2 - angle 2 = angle 2 + angle 3 + angle 4 - angle 2 <--- subtracts angle 2 from both side

angle 1 = angle 3 + angle 4
