Please help explain this. I've tried really hard but I'm still confused. I have to finish this soon and I really need help with this. Thank you so much. Quadrilateral ABCD is an isosceles trapezoid, with bases and A circle is inscribed in the trapezoid, as shown below. (In other words, the circle is tangent to all the sides of the trapezoid.) The length of base is 2x, and the length of base is 2y. Prove that the radius of the inscribed circle is .
