hey, alright so i'm suppose to add these vectors together and find the resultant and angle of the resultant without drawing a scale diagram, so using trig. i keep getting the wrong answer. the answer is suppose to be 167m ( not sure of the angle ) and this is what im getting v1 = 712m at N42degW v2 = 536m at S84degE v3 = 629m at S14degW v1 y= +529.12 x= +476.42 v2 y= 56.03 x= +533.06 v3 y= 610.32 x= 152.17 so after doing all the calculations i get a resultant of 868m at south 81 degrees west. any help would be greatly appreciated, thanks!
