Question 745773: Hello, I have this problem where in a parallelogram, one obtuse angle = 225-2x. The x variable represents an acute angle. As you know all the angles of a quadrilateral added up equals 360 degrees. And the angles opposite eachother are equal. I have tried inputting some angles for x such as 45, 35, and 25 but none have worked. Please get back to me ASAP!! I need to know how to figure it out for a test tomorrow! ~Dani
