# Resultant Help

A 60-N force is acting at 30° east of north and a second 60-N force acting in the direction 60° east of north are concurrent forces. Determine the resultant of the forces.

Using the Law of Cosines:
c²=a²+b²-2ab(CosC)
c²=13435.38
c=115.91 N for the magnitude of the resultant

Then, for the direction, I have no idea what to do.

Can someone check what I have done so far and explain how to get the direction? Thanks...

$$\frac{\sin A}{a} = \frac{\sin B}{b}$$
