procedural memory

Explanation:

The procedural memory is where we keep, the more or less automatic learning, escaping consciousness. Essentially motor skills and processes, such as writing or cycling. No one thinks of the sequence of movements we have to perform so that we can ride a bicycle, nor can we describe in words how to do it. It's automatic, which is beyond our consciousness, so we don't need to think to do it.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
