No, if \vec a = \vec b + \vec c then we can not conclude that  |\vec a| =| \vec b |+| \vec c | .

the condition    \vec a = \vec b + \vec c satisfies in the triangle.

also, in a triangle,  |\vec a| <| \vec b |+| \vec c |

Since, the condition |\vec a| =| \vec b |+| \vec c | is contradicting with the triangle inequality, if\vec a = \vec b + \vec c  then we can not conclude that  |\vec a| =| \vec b |+| \vec c |
