прости но я знаю Русский плохо и поєтому буду писать на Украинском

Объяснение:

якщо вони різні то ці кути суміжні, вводимо х і отримуємо рівняння:

х + х + 61° = 180°

2х = 119°

х = 59,5°

тоді менший кут 59,5°, а більший 120,5°.

відповідь: 59,5, 120,5, 59,5, 120,5.

вводимо х і отримуємо рівняння:

х + 2х = 180°

3х = 180°

х = 60°

тоді менша сторона 60°, а більша 120°

відповідь: 60°, 120°.
