With the origion of the point on which the two forces are applied.
The vertial force of 6500 N can be expressed in vector form as,
The truck on the left with an 8300 N for at a 10 degree angle above the x-axis needs a polar angle conversion. The x-coordinate is 8300 cos (10) = 8174. The y-coordinate is 8300 sin (10) = 1441.
Thus, in vector form it can be expressed as,
Now you add then and have a resultant.
