Mapel:mathbidang: sudut
jawab:
<AOD=8x+30+2x
180°=10x+30
10x=180-30
10x=150°
x=150/10
x=15°
jadi <AOB
=8x
=8×15
=120°
good luck:)

Mapel : MatematikaMateri : Besar Sudut
Sub Materi : Menghitung Besar Sudut
————————————————————
Besar sudut pelurus = 180°
180° = 8x + 30° + 2x
180° = 10x + 30°
180° - 30° = 10x
150° = 10x
10x = 150°
x = 150° / 10
x = 15°
<AOB = 8x°
<AOB = 8 (15)°
<AOB = 120° ✔️
Semoga bermanfaat.....
