I really need help on this question! Thank you!

KIM [24]

Answer:

A

Step-by-step explanation:

We know the following:

$OE=5\\\\FG=4\\\\EF=8\\\\$

so the segment EF is equal to

$EF=EG+GO+OF\\\\$

and here we can do a trick :)

$EF=(EG+GO)+GO+(OF+OG)-2GO\\\\$

you see it's the same

$EF=EO-GO+FG\\\\$

now we plug the values given

$8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1$

so it's option A
