Answer:
The Option B). 340 is correct.
Step-by-step explanation:
Co-terminal angles : The angles who has same terminal or initial sides are known as terminal angles.
So, in order to find measure of co-terminal angles we add or subtract the complete angle of 360° formed at a point.
Now, the measure of an angle is given to be 20°
To find : Least positive Co-terminal angle of 20°
Since, we need to find least positive co-terminal angle we subtract 20° from 360°
Required co-terminal angle measure = 360° - 20°
Hence, measure of co-terminal angle of 20° = 340°
Therefore, Option B). 340 is correct.
