Consider a right triangle AQC with length of sides being x,y and z where y represents the hypotenuse , Which of these represent the radius of the circle which is inscribed in triangle AQC Choose the correct option:
A) [A] x+y+z/3
B) [B] x-y+z/3
C) [C] x-y+z/2
D) [D] (x^2 + y^2 + z^2)/3
E) [E] cannot be determined
