Sin 75°= jawab dengan benar ya

[tex] \sin(75) = \sin(45 + 30) \\ = \sin(45) \times \cos(30) + \cos(45) \times \sin(30) \\ = \frac{1}{2} \sqrt{2} \times \frac{1}{2} \sqrt{3} + \frac{1}{2} \sqrt{2 } \times \frac{1}{2} \\ = \frac{1}{4} \sqrt{6} + \frac{1}{4} \sqrt{2} \\ = \frac{1}{4} ( \sqrt{6} + \sqrt{2} )[/tex]
