Can any one me answer this math question ?

find the distance between points e and g (the red line) on the graph below using the pythagorean theorem. i attached it below. hope it comes through.

The answer is 4*\sqrt(2), or 5.7 if rounded to the nearest tenth digit. Notice that this is a right triangle (F is the right angle). The length of FG and FE are both 4 units on the diagram. Therefore, according to the Pythagorean theorem, the length of EG is \sqrt(4^2+4^2)=4*\sqrt(2), which is about 5.7.
