what is m2DBC?

Justify your reasoning.

O Using the Angle Addition Postulate, 20+ m2DBC = 80. So, m2DBC = 60° using the subtraction property of equality

O Using the Angle Addition Postulate, 20 + 80 = m_DBC. So, m DBC = 100° using the addition property of equality.

O Using the addition property of equality, 20 + 80 = 100, so mzDBC = 100°.

O Using the subtraction property of equality, 80 - 20 = 60, SO MZDBC = 60°
