    Let East direction be the positive x axis and North the positive y axis

    Component is the horizontal (x) direction = (Magnitude) x (Cos phi)
    Component is the vertical (y) direction = (Magnitude) x (Sin phi)

    a) 70 LBS AT AN ANGLE 90 DEGREES N OF WEST
    90 degrees N of West is also 90 degrees from the positive x direction

    Magnitude = 70 ...
