You can put this solution on YOUR website! Find the measure of the reference angle for 400 degrees 
 The angle should be less than 360 degrees since a full circle is 360 degrees.
 So 400-360=60 degrees.
 
 Another example let's say we have an angle of 145 degrees, then its reference angle is 180-145=45 degrees.  So reference angles need to be less than 90 degrees.
 
 Another example let's say we have an angle of 215 degrees. Then its reference angle is 215-180=45 degrees.
 
 I hope the above steps were helpful.
