    answer gives in magnitude. you only give negative values whe they are in the opposite plane. e.g north + south -, or even north east and south west

    You just resolved as if x were to the left ~ (40sin60 - 24cos30) would be the correct working, but you know it should be positive anyway, so if you end up with a negative answer you can usually assume it's wrong :3

    I'm a bit confused, aren't we supposed to always assume that 'north' and 'east' is positive?

    You are generally supposed to assume so yes, as it's the positive on the x/y axes, however you didn't follow that in your answer. It should be ~

    X + 24cos30 = 40sin60 (equating positive and negative forces)

    X = 40sin60 - 24cos30 (rearranging for X)

    You just had an error with which way round to resolve your forces :cute:
