As in the three preceding problems a 30-60-90° triangle is joined to a 45-90-45° triangle, long side to short side to form a composite quadrilateral. Two congruent circles are fitted that are each tangential to two sides of the quadrilateral and are tangential to each other. The diagram is shown with the 45° angle at the top and the right angle at the bottom. The circles are side by side in the diagram and fit precisely. What is the radius of the circles? Scale the diagram as convenient for your calculations.
