What is m∠abc? justify your reasoning.
> using the addition property of equality, 40 + 15 = 55, so m∠abc = 55°.
> using the subtraction property of equality, 40 − 15 = 25, so m∠abc = 25°.
> using the angle addition postulate, 15 + m∠abc = 40. so, m∠abc = 25° using the subtraction property of equality.
> using the angle addition postulate, 15 + 40 = m∠abc. so, m∠abc = 55° after simplifying.
