Find the measure in degrees of the least positive angle that is coterminal 400
To find the least positive coterminal angle of 400 degrees, we can subtract multiples of 360 degrees until we reach an angle less than 360 degrees.
400 degrees - 360 degrees = 40 degrees
Since the resulting angle, 40 degrees, is less than 360 degrees, it is the least positive coterminal angle of 400 degrees.
