Answer:
The reference angle for an angle whose measure is 260° is 60°
Explanation:
Reference angle is a smallest and positive acute angle that can be formed by the terminal side with x axis.
Given angle measure is 260 degree
260 degree lies in third quadrant.
The x axis close nearest to 260 degree is 180 degree
To find reference angle we subtract 180 from 260 degree
The reference angle for an angle whose measure is 260° is 60°
