Solution Steps

Step 1: Set up the equation

The given figure is a rectangle. In a rectangle, opposite sides are equal in length. Therefore, EF = DG and ED = FG. So, $x = 2x - 10$.

Step 2: Solve for x

$x = 2x - 10$ Subtract $x$ from both sides: $0 = x - 10$ Add $10$ to both sides: $10 = x$ So, $x=10$.

Step 3: Find EF

The length of EF is given by $x$. Since $x=10$, the length of EF is 10.

Final Answer:

The length of EF is 10.
