Find the angle of least positive measure coterminal with 128

Find the angle of least positive measure coterminal with 1287 degree.

Solution

Solution:

To check what multiple of 360 degrees to be subtracted, divide 1287 by 360

=>1287/360 = 3.57

Now, 360*3 = 1080

=> 1287 - 1080 = 207

Least positive co terminal angle of 1287 degrees is 207 degrees

Answer is 207 degree
