Three vectors, each have a magnitude of 30 units, have their tails at the same oint and are directed 120 degrees from each other. Make a statement concerning the sum of these three vectors.

a) the sum vector is 0

b) the sum vector is greater thatn 30

c) the sum vector is equal to 30

d) the sum vector is less than 30

c) would be the correct answer right? I did v=sqrt(v_x^2 +v_y^2) and got 29.9993 which is quite close to 30.
