Bab Trigonometri
Matematika SMA Kelas X

3 tan (2x + 120°) = √3
tan (2x + 120°) = (√3)/3

2x + 120° = 30° + 1 x 180°
2x = 210° - 120°
x = 90°/2
x = 45°

2x + 120° = 30 + 2 x 180°
2x = 390° - 120°
x = 270°/2
x = 135°

2x + 120° = 30° + 3 x 180°
2x = 570° - 120°
x = 450°/2
x = 225°

2x + 120° = 30° + 4 x 180°
2x = 750° - 120°
x = 630° / 2
x = 315°

HP = {45°, 135°, 225°, 315°}
