Use the properties of parallel lines to solve the problem.If m 
n and m?6 = 123°, what are the measures of the other angles?
A. m?2 = m?4 = m?8 = 123° , m?1 = m?3 = m?5 = m?7 = 33°
B. m?5 = m?7 = m?8 = 123° , m?1 = m?2 = m?3 = m?4 = 57°
C. m?2 = m?4 = m?8 = 123° , m?1 = m?3 = m?5 = m?7 = 67°
D. m?2 = m?4 = m?8 = 123° , m?1 = m?3 = m?5 = m?7 = 57°
