$Sudut AOB = 180°$

$\text{[math]}$

$cal Maka,$

$cal AOB = AOC + BOC$

$cal 180° = 5a + 60 + 3a$

$cal 180° = 8a + 60$

$cal 8a = 180° - 60$

$cal 8a = 120$

$cal a = 120 ÷ 8$

$cal a = 15$

$\text{[math]}$

$sf AOC = 5a + 60$

$sf AOC = 5(15) + 60$

$sf AOC = 75 + 60$

$blue {boxed{sf AOC = 135°}}$

$\text{[math]}$

$sf BOC = 3a$

$sf BOC = 3(15)$

$blue {boxed{sf BOC = 45°}}$

Jawab:

∠AOC=135°

∠BOC=45°

Penjelasan dengan langkah-langkah:

180=5a+60+3a

180-60=8a

120=8a

a=15

∠AOC=5(15)+60=135°

∠BOC=3*15=45°
