Explicație pas cu pas:

23°45'56'' + 12°34'45'' = 35°79'101'' = 35°80'41'' = 36°20'41''

25°12'20'' - 10°30'40'' = 24°72'20'' - 10°30'40'' = 24°71'80'' - 10°30'40''

= 14°41'40''

12°15'15'' * 7 = 84°105'105'' = 84°106'45'' = 85°46'45''

175°36'30'' : 13 = 169°396'30'' : 13 = 169°390'390'' : 13 = 13°30'30''

_______________

x = 70° - 40° = 30°

_____________

x + 60° + x = 90°

2x = 90° - 60° = 30°

x = 30° : 2 = 15°

_____________

3x + 90° + 2x = 180°

5x = 180° - 90° = 90°

x = 90° : 5 = 18°

______________________

30° + x + 35° = 90°

x + 65° = 90°

x = 90° - 65° = 25°

___________

x + 70° + x = 150°

2x = 150° - 70° = 80°

x = 80° : 2 = 40°

___________

x + 30° + 3x + x = 180°

5x = 180° - 30° = 150°

x = 150° : 5 = 30°
