**Steve**, Monday, October 1, 2012 at 11:16amletting home be H, pitcher be P, 2nd base be S, we have triangle HSF where

HP = 16.8

HF = SF = 22.4

we want d = PF

d^2 = 16.8^2 + 22.4^2 - 2(16.8)(22.4)cosH

Now, the diagonal from HS to 2nd base is 22.4√2 = 31.7m

In triangle HSF,

22.4^2 = 31.7^2 + 22.4^2 - 2(31.7)(22.4)cosH

cosH = .7076

Note that H is not quite 45°, since P is not quite at the midpoint of HS.

So, now we have

d^2 = 16.8^2 + 22.4^2 - 2(16.8)(22.4)(.7076)

d = 15.85m
