sin (x-30°)=sin 90°,0°<=×<=360°​

Jawaban:

K1 : x - 30° = 90° + k. 360°

k0 = x - 30° = 90° + 0. 360°

x = 90° + 30°

x = 120° (M)

k1 = x - 30° = 90° + 1.360°

x = 120° + 360°

x = 480°(TM)

K2 : x - 30° = (180° - 90°) + k.360°

k0 = x - 30° = 90° + 0.360°

x = 120° (M)

k1 = x - 30° = 90° + 1. 360°

x = 120° + 360°

x = 480° (TM)

HP : {120°}
