You guys on this forum are the best! Thank you!

Witch cosine rule? The Law of Cosines?

Ah, I see what you mean. Thank you so much!

Okay, I understand finding the force between the two adjacent ones. No problem. And I get that the other components are fractions of them, but how would I go about calculating them simply?

I understand that part. The part I don't understand is how to separate each vector into its components. I only have the magnitude with no given angles. Looking at the hint, I need to play around with some trig. But I can't see how to incorporate the identity it hints at. And I can't use 697N as...
