Given angle is 1.8 radian.
Graphing in degree form is easier than in radian form so let's convert given angle 1.8 radian into degree.
We know that [tex] \pi [/tex] radian = 180 degree
or 1 radian = [tex] \frac{180}{\pi} [/tex] degree
Then 1.8 radian = [tex] \frac{180}{\pi}*1.8 [/tex] degree
1.8 radian = 103.132403124 degree
which is little more than 103 degree.
Now we can easily graph this angle starting from x-axis in anticlockwise direction as shown in attached picture.
