Jawaban:
a. 80°
b. 100°
c. 100°
Penjelasan dengan langkah-langkah:
Jika menghadap busur yg sama
sudut 1 putaran = 360°
sudut berpelurus = 180°
sudut yang bertolak belakang besarnya sama
..
a. POS = 2 × PQS
POS >< QOR
maka :
QOR = 2 × QPR
QOR = 2 × 40
QOR = 80
POS = QOR = 80°
b. POQ = 180 - QOR
POQ = 180 - 80
POQ = 100°
c. ROS >< POQ
ROS = POQ = 100°
