Explanation of Solution
Given information :
From the given image of angle we can observe that the angle is in I quadrant.
It is close to the axis of I quadrant and is moving anticlockwise. First the angle completed the whole
Covering whole circle is
As it is close to axis we cannot determine the exact value of the angle. We can make a rough guess.
Hence given angle is equal to
