Solution Summary

Finds the magnitude and the direction of the resultant force.

Solution Preview

Let the direction of the 53 LBS force be the x axis
Angle between the two forces = 114 degrees

x component of the 75 LBS force= 75 Cos 114 = -30.51 LBS
y component of the 75 LBS force= 75 Sin 114 = 68.52 LBS

Total force in the x direction= 22.49 LBS =53-30.51
Total force in the y direction= 68.52 LBS

Resultant force = square root of {(x component)^2 + (y component)^2}= ...
