For two line segments to be parallel, their slopes must be equal.
Therefore slope of AB must be equal to slope of CD
which is, option 3
<span> (y4-y3)/(x4-x3)=(y2-y1)/(x2-x1)</span>
C. Because complementary angles are two angles whose sum equals 90 degrees so do 90-40=50 then 50x2= 100
The answer is 2.34 x 10-11 g
