Vector

the magnitude is sqrt(23^2+11^2)

=sqrt(650)

=25.5 units

the direction is -(180-tan^(-1)(y/x))

tan^(-1) (y/x)= tan^(-1) (23/11)=64.4 degrees

hence the is -(180-64.4)

=-115.6 degrees.

note: the angle is created by the vector and horizontal line. the angle should lie between -180 and 180
