see the attached figure to better understand the problem
Step 
in the triangle ABC
<u>Find the distance AC</u>
we know that
In the right triangle ABC

solve for AC


substitute the values


Step 
in the triangle DEF
<u>Find the distance DF</u>
we know that
In the right triangle DEF

solve for DF


substitute the values


Step 
Find the value of x
we know that
the value of x is the difference between AC and DF


round to the nearest meter-------> 
therefore
<u>the answer is</u>
The value of x is
