Here you are. Read the filename. That's what you are
Giving this to you because I'm procrastinating massive lab report due for tomorrow morning

Right:
Force up due to the tension of the rope is
F_up = 8cos(50) = 5.1423 N
Downward force due to gravity mg = 0.3 x 9.8 = 2.94 N
Net upward force = F_up - mg = 2.2023 N
If, from that, you can't get the net magnitude of the force, you shouldn't be sitting that exam.
