Answer:

\Huge\boxed{D.14.6}

Step-by-step explanation:

Hello There!

We can solve for x using trigonometry

More specifically the law of sines

In the image you can see that a side length divided by sin(its opposite angle) is equal to another side length divided by sin(its opposite angle)

so to find x we use this equation

\frac{x}{sin59} =\frac{17}{sin90}

step 1 multiply each side by sin 59

now we have

x=\frac{17sin59}{sin90}\\x = 14.6

so we can conclude that x = 14.6
