Answer 1

Answer:

Step-by-step explanation:

Let the three no. be x, y and z.

x + y + z = 10 and x^2 + y^2 + z^2 = 38

(x + y + z)^2 = x^2 + y^2 + z^2 +2xy + 2yz + 2xz

10^2 = 38 + 2(xy + yz + xz)

38 + 2(xy + yz + xz) = 100

       2(xy + yz + xz) = 100 - 38

                               = 62

            xy + yz + xz = 31
