A line is perpendicular to x + 3y – 4 = 0 and has the same x-intercept as 2x + 5y – 20 = 0. Find an equation for the line.

Determine whether angle-angle-angle (aaa) is a valid means for establishing triangle congruence. if it is a valid criterion, explain why. if it is not valid, use geogebra to create a counterexample demonstrating that it doesn’t work and give an explanation. if you construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.
