Sin x = 3/10 find sin 2x

Answer: 34.92

Step-by-step explanation:

Sin x = ³/₁₀

Sin x = 0.30

Since we are determining the value of x,

x = sin⁻1 (0.30), this is called the inverse of sin or arc of sine, this could be calculated using your calculator by pressing the second function or the shift on the calculator and then press the sin⁻1

Therefore

x = 17.46

2x = 17 46 x 2

= 34. 915

≅ 34. 92
