You forgot to include the images Grinning Face with Smiling Eyes

I found a similar question, and solved it for you instead. Feel free to upload the actual image if it happens to be different.

That is the magnitude, what's highlighted. Magnitude is what you report without an angle. Do you mean you also need the angle?

Sure:

tan(theta)=opp/adj=0.4/0.3

now take the inverse tan of 0.4/0.3

tan^(-1) (0.4/0.3) = 53.1 degrees

Oh... 53.1 degrees is the same as 36.9 east of north OR 53.1 north of east
