A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exerts a force of 1850 pounds in a westerly direction. The other bulldozer pushes the piling with a force of 3250 pounds in a northerly direction. What is the direction of the resulting force upon the piling, to the nearest degree?

 I think it is just

North atan (1850÷3250) west

$$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}^{\!\!\mathtt{-1}}{\left({\frac{{\mathtt{1\,850}}}{{\mathtt{3\,250}}}}\right)} = {\mathtt{29.649\: \!863\: \!507\: \!576^{\circ}}}$$

 

Resultant direction is    $$N30^0W$$
