Find the least positive angle measurement that is coterminal with - 80°

280 is the answer.

Step-by-step explanation:

Angles are said to be coterminal when the sum of angles 360 degrees.

-80 ± 360

Since its asking for positive angle, therefore

-80+360 = 280 degrees

Least positive angle measurement = 280°

Step-by-step explanation:

Given in the question

angle = - 80°

Co terminal angles are angles whose difference differs by multiple of 360°

To solve this all we have to do is add or subtract 360° over and over again until we get answer between 0° and 360°

-80° + 360° = 280°
