Express the angle 380° in radian measure.

 The radian measure of the given angle is

Step-by-step explanation:  We are given to express the following angle in degree measure in radian measure :

We know that

the relation between degree measure and radian measure of an angle is as follows :

So, we have

Therefore, we get

Thus, the required radian measure of the given angle is
