Penjelasan dengan langkah-langkah:
7x - 16° = 5x + 14°
7x - 5x = 14° + 16°
2x = 30°
x = 15°
5x + 14° + 7y° = 180°
5(15°) + 14° + 7y° = 180°
75° + 14° + 7y° = 180°
7y° = 180° - 89°
7y° = 91°
y° = 91° : 7
= 13°
Jadi, x = 15° dan y = 13°
7x - 16 = 5x + 14
7x - 5x = 16 + 14
2x = 30
x = 15
5x + 14 + 7y = 180°
(5x × 15°) + 14 + 7y = 180°
75° + 14° + 7y = 180°
7y = 180° - 89
7y = 91
y = 13
