Answer : The value of x is 100.
Step-by-step explanation :
According to the question, the FH makes a line in which point G is present in between the line FH.
The diagram is shown below.
Given:
FG = (2x) meters
GH = 1000 meters
FH = 1200 meters
Now we have to calculate the value of x.
As we know that:
FH = FG + GH
Now putting all the given values in this expression, we get:
1200 = 2x + 1000
1200 - 1000 = 2x
200 = 2x
x = 100
Therefore, the value of x is 100.
