the magnitude of 2 vectors are 4 and 5 units and the angle b/w them is 30,taking first vectoron x-axis.find the magnitudeof resultant vectorand its direction?

  • vector addition -

    The x component of the resultant is
    Rx = 4 + 5 cos30 = 8.330
    The y component of the resuoltant is
    0 + 5 sin30 = 2.500
    The resultant magnitude is
    sqrt[(8.33)^2 + (2.5)^2] = ___
    The angle from the x axis is tan^-1(2.55/8.33)= ___
