A farmer wants to fence off his four-sided plot of flat land. He measures the first three sides, shown as A, B, and C in Figure 3.62, and then correctly calculates the length and orientation of the fourth side D. What is his result?

To calculate , first we will decompose each vectors in and components. Then add the components to calculate the and components of resultant vector. From this component calculate the magnitude and direction of the .

Step 3 of 5<p>Vector is making with the axis, hence the and components are,And

Vector is making with the axis, so the angle with axis is . Hence, the and components are,

And

Vector is making with the axis, hence, the angle with axis is . Hence, the and components are,

And
