3. There is an equally likely chance that a falling dart will land anywhere on the rug below. The following system is used to find the number of points the player wins.
What is the expected value for the number of points won?
TE
Black = 40 points
Gray = 20 points
White = 0 points

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.
