tentukan hp dari tan (2x-Π/6)-1=0 dan sec 3x - √2=0 dan 3 sec x + 2√3=0

tan (2x - 180/6) - 1 = 0
tan (2x - 30) = 1
2x - 30 = 45
2x = 45 + 30
x = 75/2 = 37,5
2x - 30 = 225
2x = 225 + 30
x = 255/2 = 127,5

sec 3x - √2 = 0
sec 3x = √2
3x = 45
x = 45/2 = 22,5
dan
3x = 315
x = 315/3 = 105

3 sec x + 2√3 = 0
3 sec x = -2/√3
sec x = (-2/3)√3
x = 30
dan
x = 330
