Solution 2. Let x, and y be the radius of 2 circles. Let A, B be the 2 intersecting points. Let O1, O2 be the centre of the 2 circles. We can see that triangle AO2B is equilateral. Therefore, AB=y. In triangle AO1B, apply the Law of Cosines: square of y = x2+x2-2x*x*cos30 = (2 - square root of 3) * square of x.Solution 2. Let x, and y be the radius of 2 circles.

First, have a review of this rule to calculate the area of a triangle when we know its 2 sides and the angle between the 2 sides: Area of a triangle = 1/2 * b * c * sin A where A is the angle between sides b and c. Connecting the centers of the 3 circles and you will get a 3-4-5 triangle. Its area is: 1/2 * 3 * 4 = 6.2009 AMC 12A. 2009 AMC 12A problems and solutions. The test was held on February 10, 2009.
