If m ∠ABC = 80° what is m∠DBC? Justify your reasoning.
Options:
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% O
D) Using the subtraction property of equality, 80 + 20 = 60. so m∠DBC = 60
