The center of the circumscribed circle lies on line segment and the longest side of the triangle is equal to the of the circle.

Two corresponding sides of two similar triangles are 3cm and 5cm. the area of the first triangle is 12cm^2. what is the area of the second triangle?

If x varies directly as y, and x = 7.5 when y = 10, find x when y = 4
