 Given that u and v unit vectors inclined at 60°
(2) c = 2a + 3b

(3) If u and v are both unit vectors inclined at 60° ...

d = 3a + 2b + c = 10u + 5v

|d| = $5\sqrt{7}$

I suggest you spend more time reading and stop trying to shortcut through your homework or the next course is going to kill you. Thanks from topsquark
