1. The problem statement, all variables and given/known data There are only 3 forces acting on an object. The forces are 20.0 dynes E15°, 30.0 dynes W15°, and 40.0 dynes S15°W 2. Relevant equation I've tried using the parallelogram method 3. The attempt at a solution When i did the parallelogram method i got 30^2+20^2-2*30*20*cos(115) because 15° for the drawn parallelogram 15+15=30 for 2 of the 4 total angles in every corner, then 360-30=330/2=165 for the two remaining angles that will let the Resultant be 50 dynes. After that i tried doing the same thing for the parallelogram figure but i just couldn't figure it out. I've tried looking for different equations but it wouldn't budge or maybe i'm just not seeing it simple?
