We can use trigonometric ratio to find the value of x
[tex]\sin \theta=\frac{opposite}{hypotenuse}[/tex]
From the question,
θ=22 opposite = x hypotenuse = 15
substitute the values into the formula and evaluate
[tex]\sin 22=\frac{x}{15}[/tex]
cross-multiply
[tex]x=15\sin 22^0[/tex][tex]x\approx5.6[/tex]
Therefore, the closest value is 5.6
