Please help me with this question.

I have a triangle that is not a right triangle with sides A, B, and C.(no values).The arrow's heads of A and B are joined and the arrow's head of C is in the tail of B. How do you find the resultant, the vector equation, and the direction of resultant?

Thank you so much.

The way you have described this, A IS the resultant of B and C. If these are indeed three separate vectors then the resultant summing all three is simply 2 times A in the direction of A
