Question #a00fc

Answer 1

If the 3 forces have equal magnitude, it would be 120 degrees between each force and its neighbor.

Explanation:

As I said above, 120 degrees if the 3 forces have equal magnitude.

But if the magnitudes are not equal, we would need to know those magnitudes to tell you. Edit: I agree with A08, Lami's theorem -
https://en.wikipedia.org/wiki/Lami%27s_theorem
- will yield the answer if the magnitudes are not equal.

I hope this helps,
Steve
