Sketch the angle in standard position:

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   radian = 180 degree

or 1 radian = degree

Then 1.8 radian = 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.
