it's the picture on the bottom

P= 15

Q= 25

I was wondering if this problem can be done using components of the force, instead of using the parallelogram law or the triangle rule. I'm a little confused on vectors and am having a hard time trying to find the angles of vectors in order to do the cosine law.

i tried to break them up into components and said px, py, and qy were negative while qx is positive since that is the way it looks in the photo, but i'm not coming up with the right answer.
