Para el diseño del nuevo auto los ingenieros ocupan un muelle que se comprima 16 cm al experimentar una fuerza de 1,200 N. ¿De qué valor deberá ser la constante de elasticidad para este resorte?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
