Problem: Find the resultant of the three displacement vecotrs in the drawing by means of the component method. The magnitudes of the vectors are A = 5.00 m, B = 5.00 m, and C = 4.00 m. http://img179.imageshack.us/img179/6690/picturels2.jpg [Broken] <-- there's the picture. I found the trigonometric functions of A and B. For A... 5 sin (20 degrees) = 1.71 m. 5 cos (20 degrees) = 4.70. Then for B... 5 sin (60 degrees) = 4.33. 5 cos (60 degrees) = 2.50. Am I heading in the right direction? Or am I completely off course? If I am heading in the right direction, what do I do next? Do I subtract 1.71 m from 4.33 m because it's heading in the opposite direction? The answer is 3.00 m, 42.8 degrees above the -x axis, but I have no clue how they got that answer.
