Find the magnitude of the vector that is the sum of the three vectors , , and in the figure : figure is the link

2. Relevant equations

3. The attempt at a solution

What I did was obtain A_{x}=0 B_{x}=7.5

A_{y}=-8.00 and B_{13}

My problem came when trying to get C_{x}and C_{y}.

The way the vector is placed in the figure confuses me but I got C_{y}= 12sin(25)= -10.87 since it is on the negative side, and C_{x}= 12Cos25=-5.07.

I then got the squareroot of A_{x}+B_{x}+C_{x}^2+A_{y}+B_{y}+C_{y}^2

Did I create the triangle wrong? If so how can I make sure to not make this same mistake
