Question

50 poin nih kak,
harus pale CARA yaa, kalo enggak aku laporin

Answer 1

2 sin² x - 7 sin x + 3 = 0
(2 sin x - 1)(sin x - 3) = 0
2 sin x -1 = 0 atau sin x - 3 = 0
sin x = 1/2 atau sin x = 3 (TM) krn > 1

sin x = 1/2 = sin 30 = sin 150
x = 30 atau x = 150
X = 30/180  π  atau x = 150/180 π
x = π/6 atau x = 5π/6
