Help on vector wierd problem

  1. Dec 17, 2008 #1
    Two component vectors with magnitude of 8 and resultant magnitude of 10. What must be the angle between the two component vectors?

    I really dont know where to start on this. Any help would be greatly appreiated!

    P.S. need by tomorrow!

    Do you have any formulas to compute magnitude of the component vectors and the resultant magnitude?
