What is the fraction 20/21 in simplest form

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

Use the converse of the side-splitter theorem to determine if tu || rs. which statement is true? line segment tu is parallel to line segment rs because 32/36 = 40/50 line segment tu is not parallel to line segment rs because 32/36 not equal 40/50. line segment tu is parallel to line segment rs because 32/36 = 40/50. line segment tu is not parallel to line segment rs because 32/36 not equal 40/50 .
