An artist is making a scale model of a statue she has been commissioned to create. the model is 2 feet tall. the actual statue will be 15 feet tall. what is the scale of the model to the actual statue?

In what form is the following linear equation written y=9x+2

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.

Which geometric principle is used to justify the construction below?
