How many times does your heart beat during your lifetime? round the answer to the nearest power of 10 and then express your answ
babymother [125]
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!
