In the diagram, p1p2 and q1q2 are the perpendicular bisectors of line ab and bc , respectively. a1a2 and b1b2 are the angle bisectors of angle a and b , respectively. the center of the inscribed circle of δabc is point , and the center of the circumscribed circle of δabc is point .

Find the value of a. the diagram is not to scale. a quadrilateral is drawn. the upper and lower sides are parallel. the interior angle in the upper left corner is labeled a degrees. the angle in the upper right corner is labeled 113 degrees. the angle in the lower right corner is labeled b degrees. the angle in the lower left corner is labeled 36 degrees. a. 36 b. 144 c. 54 d. 126

The ratio pv to nrt is plotted against pressure for ch4 at 0°c and 200°c. why does the curve for 0°c drop below the horizontal line for an ideal gas whereas the curve for 200°c does not?

Me find the value of x each figure.
