If five forces act towards the same point on a body at angles of 60, 120, 180, 240 and 270 degrees and their respective magnitudes are 60N, 40N, 30N, 25N and 20N. Determine whether this system of forces is in equilibrium; find the resultant.

You have to add them as vectors. Not knowing from where the angles are measured and in what direction, I can't help.
