**Reiny**, Monday, April 1, 2013 at 9:53pmI have a triangle with sides 60 and 400 and the contained angle is 70°

let the resultant be R

R^2= 60^2 + 400^2 - 2(60)(400) cos70°

= 147183.0331

R = 383.64 mi/h

finding the angle opposite the 70°

sinØ/60 = sin70/R

sinØ = .14696..

Ø = 8.45°

so the compass heading is 250 + 8.45 = 258.5°
