Explicație pas cu pas:

23°10' + 31°2' + 10°23' = 64°35'

_____________

175° - 134°20' + 6°30':3*2 = 43°

6°30' = 180' + 30' = 210'

210' : 3 * 2 = 70' * 2 = 140' = 2°20'

175°+ 2°20' = 177°20'

177°20'- 134°20' = 43°

________________

(1° + 2° + 3° + ... + 13°) - 90° = 91° - 90° = 1°

_______________

(1° + 2° + 3° + ... + 14°) : 21 + 85° = 105° : 21 + 85° = 5° + 85° = 90°

___________

1°1' + 2°2' + 3°3' + .... + 16°16' = 138°16'

1 + 2 + 3 + .... + 16 = 136

136' = 2°16'

136° + 2°16' = 138°16'

___________________

180° - (2°2' + 22°22' - 24°24') - (40°40' - 40') = 180° - (24°24' - 24°24') - 40° =

= 180° - 40° = 140°
