Three forces act on an object while the object remains at rest $($zero velocity and zero acceleration$).$ The first force is $26\mathrm{.}0$ newtons and is in a direction $125\mathrm{.}0$ degrees from the positive $x-$axis. The second force is $17\mathrm{.}0$ newtons and is directed $205\mathrm{.}0$ degrees from the positive $x-$axis. Calculate the magnitude of the third force vector.

Calculate the direction of the third force vector as an angle measured from the positive x $-$axis.
