Answer:

x = 8.8

EF = 22.6

Step-by-step explanation:

The given figure is of a rectangle.

We know that the opposite sides of a rectangle are parallel and equal.

So,

  • 3x+5 = 7x-39
  • 3x-7x = -39-5
  • -5x = -44
  • x = -44/-5
  • x = 8.8

Now, finding EF

  • 7x-39
  • 7×8.8-39
  • 61.6-39
  • 22.6
