North component: y = 15.0 m * sin 55.0º = 12.3 m West component: x = 15.0 m * cos 55.0º + 7.00 m = 15.6 m
so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West
and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North
Hope this helps!

It is kind of a strange question but by the process of elimination, I would go with petrification.
Its called petrified wood.
