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!
        
             
        
        
        
The deer and wolf population would decrease because the deer have less plants to feed on while already being eaten by the wolves, and eventually the wolves will have less deer to feed on which will decrease their population
