Determine the magnitude of the vector sum V 
V1  V2 and the angle x which V makes with the
positive x-axis. Complete both graphical and algebraic
solutions.
V1 = 10
V2 = 12

What do YOU think ?
While we're happy to HELP we won't do all the work for you.
Show us what you have done and where you are having problems..

There is an angle 60 to pointet on V2.
I have tried a lot of ways but can't get it rigth.
Need a rule or a formula. To solv it please.
If its possibel
