Find an equation equivalent to r= 1+2 sine in rectangular coordinates.
a x² + y² - x + y² + 2y
c. x+y - 12 + y2 + 2y
b. x+z? - sx + y² + 2x
d. x² + y² - x² + 2? + 2x

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
