Given :
Magnitude of vector is 30 units.
Direction of vector from x-axis is 116°.
To Find :
The component form of the vector.
Solution :
We know, vector in component form is given by :

Putting given values,

Hence, this is the required solution.
you could use Set Builder or Interval notation, as in the example you saw above.
you could also use a graph for the inequality, and graph wise, you can do it on a cartesian plane or an interval one on a Line Number.
