Resolving forces of a particles in equi

[hasnain721]

Homework Statement

Forces of magnitude 4N, 5N and 8 N act on a particle in directions whose bearings are 000° , 090° and 210 ° respectively. Find the magnitude of the resultant force and the bearing of the direction in which it acts

The Attempt at a Solution

I think that the resultant force is in between the 4N and the 5N forces. However I am not sure as i guessed that. I am not sure what to do next.


Plz help
Thanks

Force is a vector therefore has magnitude and direction. Break the forces into its components.

how?

right F = Fx + Fy where Fx = Fcos(theta) + FSin(theta) relative to the coordinate system. Once you find all the components you can add all the Fx's and Fy's
