An artist is cutting a piece of metal as shown. what is the angle measure of the piece left over?

Arrange these numbers from least to greatest 3/5 5/7 2/9

Plz i beg u asap ! what is the equation of this graphed line? enter your answer in slope-intercept form in the box.

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.
