Confused on question in screenshot.

Answer 1

Answer:

The right answer is the second option, 9,747.

Step-by-step explanation:

$EG^2 = DG*FG \\ EG^2 = 5*14 \\ EG = \sqrt{70}$

Now let's find DE (Pythagorean theorem).

$DE^2 = DG^2+EG^2\\ DE = \sqrt{25+70} \\ DE = \sqrt{95}$

$\sqrt{95} =9,7467... = 9,747$
