187°19'8"-21°41'39". 8"-39": borrow 60 seconds from minutes to make 68"-39"=29". Add 1 to minutes to compensate for borrowing: 19'-42' or 18'-41'; borrow 60 minutes from degrees to make 79'-42' or 78'-41'=37'. Finally add 1 to the degrees to compensate for borrowing: 187°-22° or 186°-21°=165°. Result: 165°37'29".
