1° = 60'
1' = 60''
1) 121° + 13° 42' = (121 + 13)° 42' = 144° 42'
2) 62° 11' + 37° 12' = (62 + 37)° (11 + 12)' = 99° 23'
3) 54° 9' + 2° 51' = 56° 60' = 57°
4) 43° 43' + 46° 17' = 89° 60' = 90°
5) 137° 39' + 26° 26' = 163° 65' = 164° 5'
6) 18° 37' 42'' + 39° 24' 18'' = 57° 61' 60'' = 57° 62' = 58° 2'
7) 36° 17' 26'' + 53° 42' 34'' = 89° 59' 60'' = 89° 60' = 90°
8) 84° 12'' + 36° 19' 54'' = 120° 19' 66'' = 120° 20' 6''

Пошаговое объяснение:
1) 121°+13°42`=134°42`
2) 62°11`+37°12`=(62°+37°)+(11`+12`)=99°23`
3) 54°9`+2°51`=(54°+2°)+(9`+51`)=56°+60`=56°+1°=57°
4) 43°43`+46°17`=(43°+46°)+(43`+17`)=89°+60`=89°+1°=90°
5) 137°39`+26°26`=(137°+26°)+(39`+26`)=163°+65`=163°+1°+5`=164°5`
6) 18°37`42``+39°24`18``=(18°+39°)+(37`+24`)+(42``+18``)=57°+61`+60``=
= 57°+1°+1`+1`=58°2`
7) 36°17`26``+53°42`34``=(36°+53°)+(17`+42`)+(26``+34``)=89°+59`+60``=
= 89°+59`+1`= 89°+60`=89°+1°=90°
8) 84°12``+36°19`54``=(84°+36°)+19`+(12``+54``)=120°+19`+66``=120°+19`+1`+6``=
= 120°20`6``
