CORRECTION: Please note that at 4:22 I wrote down and said to ADD (2)(3)(1.615)cosθ. This expression is SUBTRACTED, NOT ADDED. Therefore, when you plug in (-2)(3)(1.615) into the denominator, you are automatically yielded with the final answer shown here, 38.26°. I apologize for any confusion.

Can I do it without the cosine rule?

Hi! would this still be possible to solve if only FA and its angle were the only given?

Hello, at a minimum you would need more information, such as the magnitude and direction of the resultant force or the second force.
