Fig. 1

Three coplanar forces act at a point. The magnitudes of the forces are $5.5\text{ N}$ , $6.8\text{ N}$ and $7.3\text{ N}$ , and the directions in which the forces act are as shown in the diagram. Given that the resultant of the three forces is in the same direction as the force of magnitude $6.8\text{ N}$ , find the value of $\alpha$ and the magnitude of the resultant.
