Jawaban:
∠AOC + ∠BOC = Berpenyiku
(6x - 2)° + (5x + 4)° = 90°
6x + 5x + 4° - 2° = 90°
11x + 2° = 90°
11x = 90° - 2°
11x = 88°
x = 88°/11
x = 8°
∠BOC = 90° - (5x + 4)°
= 90° - (5(8)° + 4)°
= 90° - (40° + 4)°
= 90° - 44°
= 46°

Penyelesaian :
∠AOC + ∠BOC = Berpenyiku
(6x - 2)° + (5x + 4)° = 90°
6x + 5x + 4° - 2° = 90°
11x + 2° = 90°
11x = 90° - 2°
11x = 88°
x = 88°/11
x = 8°
Penyiku ∠BOC
∠BOC = 90° - (5x + 4)°
= 90° - (5(8)° + 4)°
= 90° - (40° + 4)°
= 90° - 44°
= 46°
