75 dan 165 adalah sudut yang tidak bernilai istimewa, sehingga harus dicarikan jalan lain untuk mendapatkan hasilnya. Rumus Jumlah dan Selisih Sinus, Cosinus, Tangent; Persamaan Trigonometri; TRIGONOMETRI; Matematika. Thus, when two angles are complementary, we can say that the sine of θ θ equals the cofunction of the complement of θ. Thus, when two angles are complementary, we can say that the sine of θ θ equals the cofunction of the complement of θ. Step 5. $$ \cos 165 ^ { \circ } $$. Rumus Jumlah dan Selisih Sinus, Cosinus, Tangent untuk mengerjakan soal ini maka rumus trigonometri yang perlu kita ketahui adalah A min Cos 2 Sin a + sin A min b per 2 selanjutnya ganti ini dapat kita ganti dengan nilai yang ada di sini 75/65 menjadi D setelah mendapatkan seperti ini minus 2 Sin 120
There are more formulas for the double angle (2 × 165°), half angle ((165/2)°) as well as the sum, difference and products of two angles such as 165° and β. sin45° = cos 45° = 1/2. tan (u) = -9/40, 3x/2
