What is m A)Using the addition property of equality, 40 + 15 = 55, so m∠ABC = 55°.
B)Using the subtraction property of equality, 40 − 15 = 25, so m∠ABC = 25°.
C)Using the Angle Addition Postulate, 15 + m∠ABC = 40. So, m∠ABC = 25° using the subtraction property of equality. D)Using the Angle Addition Postulate, 15 + 40 = m∠ABC. So, m∠ABC = 55° after simplifying.
