Jawaban:
60°
Penjelasan dengan langkah-langkah:
(3y + 30°) + 60° = 180°
3y + 90° = 180°
3y = 180° - 90°
3y = 90°
y = 30°
3y + 30° = 4x
90° + 30° = 4x
120° = 4x
30° = x
= x + y
= 30° + 30°
= 60°
Semoga membantu!
x=30°,y=40°
3y+30°+60°=180°
3y+30°=120°=>sama dengan 4x karena sudut nya bertolak belakang
3y=90°
y=30°
4x=120°
x =30°
SEMOGA MEMBANTU^_^

Jawaban:
60°
Penjelasan dengan langkah-langkah:
PERTAMA,
(3y + 30°) + 60° = 180°
3y + 90° = 180°
3y = 180° - 90°
3y = 90°
y = 30°
KEDUA,
3y + 30° = 4x
90° + 30° = 4x
120° = 4x
30° = x
KETIGA,
= x + y
= 30° + 30°
= 60°
Semoga membantu!
