see the attached figure to better understand the problem

Step $1$

in the triangle ABC

Find the distance AC

we know that

In the right triangle ABC

$tan(A)=BC/AC$

solve for AC

$AC=BC/tan(A)$

$BC=10\ m\\A=35.5\°$

substitute the values

$AC=10/tan(35.5\°)$

$AC=14.02\ m$

Step $2$

in the triangle DEF

Find the distance DF

we know that

In the right triangle DEF

$tan(D)=EF/DF$

solve for DF

$DF=EF/tan(D)$

$EF=14\ m\\D=54.5\°$

substitute the values

$DF=14/tan(54.5\°)$

$DF=9.99\ m$

Step $3$

Find the value of x

we know that

the value of x is the difference between AC and DF

$x=AC-DF$

$x=14.02-9.99=4.03\ m$

round to the nearest meter-------> $x=4\ m$

therefore

the answer is

The value of x is $4\ m$
