Answer 2

[cos x + 2sin 1/6 phi]/[sin 5/3 phi - cos phi] = 1

[cos x + 2sin 1/6(180°)]/[sin 5/3(180°) - cos 180°] = 1

[cos x + 2 sin 30°]/[sin 300° - cos 180°] = 1

[cos x + 2(1/2)]/[-1/2 V3 - (-1)] = 1

[cos x + 1]/[-1/2 V3 + 1] = 1

cos x + 1 = -1/2 V3 + 1

cos x = -1/2 V3 + 1 - 1

cos x = -1/2 V3

cos x = cos 150°

x = 150°

x = 5/6 phi (C)
