Question
I have a question about a vector addition problem using the polygon method.
Vector 1 has a magnitude of .1 and theta of 30 degrees.
Vector 2 has a magnitude of .2 and a theta of 90 degrees.
Vector 3 has a magnitude of .3 and a theta of 225 degrees.
I'm confused because if I draw vector 3's tail at the head of vector 2, the 225 degrees makes vector 3 go in the wrong direction. What am I doing wrong?
(I hope this makes sense!!)
Thank you!

225o = 180 + 45o. So the vector is 45o
below West. Therefore, it will point to
the left and downward at an angle of 45o.
The three vectors can also be drawn from
the origin.
