A. All cancel to produce the 0 vector. b. Each one cancels its opposite except the 8:00 vector which is no longer cancelled by 2:00. c. 2:00 is 1/3 of the way up from 3:00 x-axis to 12:00 y-axis so fie = pi/6 v= (cos pi/6, sin pi/6) = sqrt 3/2, 1/2 hope it helps
1 inch is 1/12 of a foot 3 inches is 1/4 of a foot Number line would be divided into 12. The first spot would be 1/12, the next would be 2/12 and so on. Make a mark at 1/12 for one inch and at 3/12 for 3 inches
