Answer:

The fraction of the labelled angle is: 2/3 of one semicircle.

In radians, it is: 2.0944 rad.

Recall:

One semicircle = 3.1416 radian

One semicircle = 180 degrees

Thus, 120 degrees of a semicircle as a fraction would be:

120/180 = 2/3

Therefore, 120 degrees equals 2/3 semicircle.

Convert to radians:

One semicircle = 3.1416 radian

2/3 semicircle = x
