Two forces act on an object. The first force has a magnitude of 17.0 N and is oriented 68.0° counterclockwise from the x axis, while the 2nd force has x and ycomponents (19.0 N, 16.5 N). Express the magnitude and direction of the net force.

F(x) =17cos6819 =
F(y) = 17sin68+16.5 =
F=sqrt{F(x)²+F(y)²}=
tanα =F(y)/F(x)=
