You can put this solution on YOUR website!
the supplementary angle add up to 180
as you know, there are 60 seconds to every minute and 60 minutes to every degree
the supplementary angle to 100 degrees 20 minutes 40 seconds will be
180-%28100deg%2B20min%2B40sec%29....take one degree from 180 and convert into minutes, and take one minute and convert into secundes
%28179deg%2B59min%2B60sec%29-%28100deg%2B20min%2B40sec%29

%28179deg-100deg%29%2B%2859min-20min%29%2B%2860sec-40sec%29
79deg%2B39min%2B20sec
so, the supplementary angle to 100 degrees 20 minutes 40 seconds is 79 degrees 39 minutes 20 seconds
