1. The problem statement, all variables and given/known data
Consider four vectors ~ F1, ~ F2, ~ F3, and ~ F4 with
magnitudes F1 = 59 N, F2 = 29 N, F3 = 11 N,
and F4 = 60 N, θ1 = 150 ◦, θ2 = −150 ◦,
θ3 = 23◦, and θ4 = −56◦, measured from the
positive x axis with counterclockwise positive.
What is the magnitude of the resultant vec-
tor ~F = ~ F1 + ~ F2 + ~ F3 + ~ F4?
Answer in units of N.


2. Relevant equations
I know you have to create vectors and add them, but I don't know how with the given information.


3. The attempt at a solution
...none.
 
you know parallelogram or triangle way of adding vectors,right?
Do it for 2 vectors first, finding their resultant, and use that and the next vector to get another resultant..... continue and you will reach the answer.
