12\,\text{N}

north,

9\,\text{N}

south, and

5\,\text{N}

east. Calculate the magnitude and direction of the resultant force. (a)

3.0\,\text{N}

due north (b)

21.0\,\text{N}

toward the

\text{north-east}

(c)

5.8\,\text{N}

directed approximately

31^{\circ}

north of east (d)

5.8\,\text{N}

directed approximately

31^{\circ}

east of north
