Answer the following questions to determine the key features of the hyperbola based on the equation shown, and then graph it. 4x2 + 8x – 9y2 – 36y – 68 = 0 a) Write the standard equation of the hyperbola.

Through non-collinear points there is exactly one plane.

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.
