An engineer is proof-reading his report and finds that he has mistakenly used micrometers as a unit of measure. His experiment showed a
measurement of 2 micrometers, but the government requires the
measurement to be in millimeters. How should the engineer record the
measurement (if there are 1000 micrometers in 1 millimeter)? *

Agraph of a trapezoid can have diagonals with slopes that are negative reciprocals and two pairs of adjacent sides that are congruent, true or false, and why

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.
