Fyodor and his three sons, Ivan, Dmitri and Alyosha, are standing exactly on the corners of a rectangular room. Fyodor is 8 meters from Dmitri and 15 meters from Ivan. What is the minimum possible distance that Fyodor could be from Alyosha, in meters?

Min possible distance =  sqrt [ 15^2 - 8^2 ]  = sqrt[ 225 - 64 ] = sqrt [ 161] ≈ 12.69 m
