Magnitude and direction of a vector

Hi,

I didn't know exactly where to put this post, but I see in the posts here that there are a lot of things similar to what I am learning.

The problem I have is:

The resultant of P and Q (both vectors_ is a force F (vector). F is 80N [N70degreesE] and P is 25N[E]. Find the magnitude and direction of Q.

My answer is: 53.5 N [N59.1degreesW].

Is this correct? I have solutions from my teacher; her process work is the same as mine but her values are different, so I just want to know if my answer above is correct. Thanks!
