Someone plz answer this one! triangle cde and triangle cfg are similar right triangles. which proportion can be used to show that the slope of ce is equal to the slope of cg? a) 4 − 3 6 − 2 = 6 − 3 9 − 2 b) 4 − 2 6 − 3 = 9 − 3 6 − 2 c) 4 − 2 6 − 3 = 6 − 2 9 − 3 d) 6 − 3 4 − 2 = 6 − 2 9 − 3

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.
