Penjelasan dengan langkah-langkah:
Sesuai sifat sudut
(5x)° + (4x + 9)° = 180°
9x° + 9° = 180°
9x° = 180° - 9°
= 171°
x° = 19°
Jadi ∠SQR = (4x + 9)°
= (4(19) + 9)°
= (76 + 9)°
= 85°
Semoga membantu, jangan lupa kasih MAHKOTA yaa, makasih loh :)
(5x)°+(4x+9)°=180°
9x+9=180°
9x=180-9
9x=171
x=171/9
x=19
SQR=4x+9
SQR=4×19+9
SQR=76+9
SQR=85
