First we write the point
we use the yellow angle to find another measures
Now we write another points to represent it
the measure of the angle is pi(for the strigth line) less yellow angle
[tex]\begin{gathered} x=\pi-\frac{\pi}{3} \\ \\ x=\frac{2}{3}\pi \end{gathered}[/tex]
then a new point is
[tex](3,\frac{2}{3}\pi)[/tex]
and we can find many values to the radians becaus if we add a turn(2pi) to the original angle we obtain a similar or equivalent angle then a secon point is
[tex]\begin{gathered} (3,\frac{2}{3}\pi+2\pi) \\ \\ \\ (3,\frac{8}{3}\pi) \end{gathered}[/tex]
