Two forces have the same magnitude "F".

What is the angle between the two vectors if their sum has a magnitude of "2F".

Please provide solution, not just the answer. Thanks!

Thank you but I don't think that I am allowed to use the law of cosines in finding the answer....is there another way to determine the angle?

The other part of the question is What is the angle between the two vectors if their sum has a magnitude of (√2)F and zero?

Thanks.

I think I have to do vector addition but I'm not sure how to.
