Answer:
The answer should be 2A/(a+b)=h
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

8
round each number to the nearest 10, then
640 ÷ 80 = 8 ← estimate
-1/2 is the slope of the line!
