Please help, I'm in a test right now, what is the resultant of the following vectors?

A 38 degrees with a magnitude of 241


B 138 degrees with a magnitude of 106


C 240 degrees with a magnitude of 136


D 347 degrees with a magnitude of 148





I know I have to add them tail to tip and them find the resultant that will balance the system.





But I'm having problems figuring out AutoCad; I just need to write down the answer, he doesn't need process shown.





For the second problem I got:





A 18 degrees at 210


B 208 degrees at 110


C 268 degrees at 135


D 347 degrees at 145





Anybody?

Please help, I'm in a test right now, what is the resultant of the following vectors?
tot = 241*cos(38) - 106*cos(42) - 136*cos(60)+148*cos(32)
