 Question 589326: Hi I need you help solving a problem for a rhombus. The question asks to solve for the values of X and Y. I'm given a rhombus with angles labeled ABCD. ∠A is (4x-y) degrees ∠B is (2x-3y) degrees ∠C is (4x) degrees and ∠D is (2x-5y) degrees. There is also an exterior angle that extends from ∠D and that exterior angle is (6x+2y) degrees. Once again the question asks to solve for X and Y, and the shape if the figure is a rhombus. I hope this a good enough explanation that someone's able to help. Thank you. Click here to see answer by Edwin McCravy(8908)
