I really need help on this question! Thank you!

Answer 1

The answer for your question is A

Answer 2

A

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
