45 PTS PLEASE HURRY Maryanne got 1 out 3 for her response. She is super upset because she thought she got the right answer. She was asked to find the GCF, what is maryanne's fault?
What is the answer to this problem?

Find the measure of angle y. round your answer to the nearest hundredth. ( type the numerical answer only) a right triangle is shown with one leg measuring 5 and another leg measuring 14. an angle across from the leg measuring 5 is marked y degrees. numerical answers expected!

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.

Angle a and angle b are both supplementary angles. what must be true about the angles?
