The difference between the angles 120° and 150° will be 30°.
Conversion means to convert the same thing into different units.
The conversion from radian to degree will be
1 radian = x · (180° / π) degree
Compare an angle having a measure of 120° with that of an angle whose measure is 5π / 6 radians.
Then convert 5π / 6 radians into degrees. Then we have
5π / 6 radians = 5π / 6 · (180° / π) degree
5π / 6 radians = 150°
Then the difference between the angles 120° and 150° will be
⇒ 150° – 120°
⇒ 30°
