How do the definitions, properties, and postulates you've learned about line segments, parallel lines, and angles to define the shapes of polygons

A. what does the point (4, 122) represent? b. what is the unit rate? c. what is the cost of buying 10 tickets?

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.
