Jawaban:

Penyelesaian :

• ∠AOC = (2x + 30)°
• ∠COD = 90° (siku - siku)
• ∠BOD = (3x + 20)°

Cari dulu nilai x

∠AOC + ∠COD + ∠BOD = Berpelurus

(2x + 30)° + 90° + (3x + 20)° = 180°

2x + 30° + 90° + 3x + 20° = 180°

2x + 3x + 30° + 90° + 20° = 180°

5x + 140° = 180°

5x = 180° - 140°

5x = 40°

x = 40°/5

x = 8°

• Besar ∠AOC

∠AOC = (2x + 30)°

= (2(8)° + 30)°

= (16° + 30)°

= (46)°

= 46°

• Besar ∠BOD

∠BOD = (3x + 20)°

= (3(8)° + 20)°

= (24° + 20)°

= (44)°

= 44°
