HELP ASAP Find the measures of the 3 angles of a triangle if the sum of the measure of
the first angle (X) and the measure of the second angle (Y) equals the
measure of the third angle (2), and if two times the measure of the first angle
is 20 degrees more than the measure of the third angle.

The step function g(x) is defined as shown. what is the range of g(x)? ***answer choices in picture.

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2

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.
