An isosceles triangle has base angles that each measure 52°
Which equation can be used to find x, the measure of
the third angle of the isosceles triangle in degrees?
A) 2X = 52
D) $2X = 180
B) 52 + 2x = 180
ED 52 + x = 180
CD 2x52 180
None of the above

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
