The product of (1/2+3/4)(1/2-3/4)(i) and divided by (2-3i) is (multiplying complex numbers)
a) 1/8 + 3i/16
b) 26/16 - 39i/16
c) -10/208 - 15i/208

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
