Homework Statement


The diagram below shows 3 vectors which sum to zero, all of equal length. What is
[itex]\vec{A}[/itex] - [itex]\vec{B}[/itex]?

Hi Ammar w! Welcome to PF! :smile:

Draw -B …

what does it look like? :wink:​
 
Thank you Andrew Mason & tiny-tim
C+A=-B // add A to the sides of the equatoin
C+2A=A-B
A-B = C+2A.
I didn't draw anything.
Thanks for let me thinking.
