1. The problem statement, all variables and given/known data

Two vectors A and B are defined as follows, A(10cm, 35degrees) and B(8cm,110degrees). Use a protractor, a ruler and graph papers to do this exercise. The lines must be drawn to scale.

a. Sketch vector A and sketch vector B using the same origin.

b. Use a different graph paper for this exercise. Use the head to tail method to sketch R=A+B. Measure the magnitude and direction of R using your ruler and protractor and record them on your sketch.

c. Use a different graph paper for this exercise. Use the head to tail method to sketch R=A-B. Measure the magnitude and direction of R using your ruler and protractor and record them on your sketch.

2. Relevant equations

im not sure.....

3. The attempt at a solution

so do i just do add or subtract the degrees and use the cos and sin format to do it and how do i suppose to do this.....I am really stuck and confuse...to be honest, my mind is blank
