Two forces act on an object. One has a magnitude of152 newtons and points at an angle of68.0° above the +x axis. The second has a magnitude of 291newtons and points at an angle of 20.0° above the +x axis. A third forceis applied and balances to zero the effects of the other two. What are the magnitude and direction of this third force? Specify thedirection relative to the negative x axis.
