In a triangle, the sum of two sides is

x

and the product of the same two sides is

y

. If

x^2-c^2=y

, where

c

is the third side of the triangle, then the ratio of the inradius to the circumradius of the triangle is

View answer and explanation

Correct option: A

\frac{3 y}{2 x(x+c)}

Option B is the correct answer because it correctly calculates the ratio of inradius to circumradius using the given conditions and trigonometric relationships.
