Ming's science beaker contains 2 liters of water. For the experiment, Kelly added 26 milliliters of liquid coloring and Ryan added another 145 milliliters of liquid soap. How many milliliters of liquid are in Ming's beaker now? Show your work.

the answer will be

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
