Please kak tlong ya berapa persamaan trogonometrinya kak kalau Tan (x-60)+1/3√3=0 k= 0,1,2,3,4,....

Tan (x - 60°) + 1/3 √3 = 0
Tan (x - 60°) = -1/3 √3
Tan (x - 60°) = Tan 150°
x - 60° = 150° + k . 180°
x = 210° + k . 180°
k = 0 => x = 210°
k = 1 => x = 390°
Jadi x = 210°

tan (x - 60) + 1/3 √3 = 0
tan (x - 60) = -1/3 √3
tan (x - 60) = tan (-30)

x - 60 = -30 + k.180
x = 30 + k.180
k= 0,x = 30°
k=1,x=210°

HP= {30°,210°}
