PQR = sudut Q itu pelurus berarti 180°sudut diluar = 100° maka sudut PQR = 180 - 100 = 80°
yang ditanya sudut PRQ
sudut segitiga = 180° maka 180 - 50 - 80 = 50° (B)
smoga membantu ^_^

Mapel : MatematikaBab : Sudut
Diketahui :
- ∠QPR = 50°
- ∠RQS = 100°
Ditanya :
- ∠PRQ = .....?
Penyelesaian :
- ∠PQR :
∠PQR = 180° - ∠RQS
∠PQR = 180° - 100°
∠PQR = 80°
- ∠PRQ :
∠PRQ = 180° - ∠QPR - ∠PQR
∠PRQ = 180° - 50° - 80°
∠PRQ = 130° - 80°
∠PRQ = 50°
Jawaban : B. 50°
Maaf Kalau Salah
