if m < abc = 80° , what is m < dbc? justify your reasoning.
a) using the angle addition postulate, 20 + m < dbc = 80. so, m < dbc = 60° using the subtraction property of equality.
b) using the angle addition postulate, 20 + 80 = m < dbc. so, m < dbc = 100° using the addition property of equality.
c) using the addition property of equality, 20 + 80 = 100, so m < dbc = 100°.
d) using the subtraction property of equality, 80 - 20 = 60, so m < dbc = 60°
