1.) Use the Triangle Rule and the Law of Cosines to find the magnitude of the resultant force $${\mathbf{F}}_R={\mathbf{F}}_1+{\mathbf{F}}_2$$. 2.) Utilizing the figure from Problem 1, decompose forces $${\mathbf{F}}_1$$ and $${\mathbf{F}}_2$$ into Cartersian components and find the resultant force $${\mathbf{F}}_R={\mathbf{F}}_1+{\mathbf{F}}_2$$ and the angle of the resultant with respect to the $$X$$ axis.
