1.	Consider a triangle ABC, where x, y, z are the length of perpendicular drawn from the vertices of the triangle to the opposite sides a, b, c respectively let the letters R, r, S, D denote the circumradius. inradius semi-perimeter and area of the triangle respectively. If (bx)/c + (cy)/a + (az)/b = (a^(2) + b^(2) + c^(2))/kthen the value of k is
