Help finding resultant force and angle

  1. Jan 20, 2009 #1
    1. The problem statement, all variables and given/known data
    hi everyone! okay so i have a few questions that i worked on. the question is, FIND THE RESULTANT FORCE AND ANGLE FOR THE FOLLOWING HORIZONTAL AND VERTICAL FORCES:
    A.) 250N, 350,
    B. 1000N, 2000N
    C 2.00KN, 1.00KN
    D 25 N, -35 N
    E. -10 N, -20N
    F -5KN, 15 KN

    2. Relevant equations
    I used a+b=c (all squared), then i used arctan TOA to find the angle, can someone please tell me if i got the answers right?

    3. The attempt at a solution
    a. force of 430 N, angle of 54.5
    b. force 2236 N, angle 63 degrees
    c. force 2236 N, angle 26.5 degrees
    d. force of 43 N, angle 35.5 degrees
    e. force of 22 N, angle 63 degrees
    f. force of 15811 N, angle 71.5 degrees

    thanks everyone!
