The diameter of one circle is represented by 12x. the diameter of another circle is represented by 6x2y. what is the ratio of the radio of the two circles?
a. 2: x3y
b. 2x: i
c. x: 2y
d. 2: xy

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
