In question 2, how do we know the direction of the resultant?? Is it always upwards? I thought it would be downwards.. I don't get it! Argh im so nervous please help me

the direction is upwards because the two adjacent forces are acting upwards but sideways (parallelogram). and the downward force is T3.
