Answer 2

x = 7.2

Explanation:

Hey There!

We can find the length of x by using law of sines

law of sines states that a side length divided by sin ( its opposite angle) is equal to another side length divided by sin (its opposite angles) so we setup an equation

`(46)/(sin90) =(x)/(sin9)`

now we can solve for x

step 1 multiply each side by sin 9

now we have

`x=(46sin9)/(sin90)\\x=7.195985392`

So x = 7.195985392

it says to round to the nearest tenth of a foot so x = 7.2
