In a right triangle ABC, right angled at vertex B, side opposite angle A, B and C are a, b and c respectively. If r is in-radius and R is the circumradius of the triangle ABC, the 2(R + r) equals
Explanation:
In a right triangle inradius (r) = (sum of two smaller sides - hypotenuse)/2 and
Circumradius (R) = Hypotenuse/2
∴ 2(R + r) = 2R + 2r = b + (a + c - b) = a + c
Hence, option (d).
