OpenStudy (nikato):

Can you draw the figure?

OpenStudy (cloverracer):

It doesn't have a figure

OpenStudy (nikato):

|dw:1409612190383:dw| this would be your figure. u dont actually need it but it would help you understand better

OpenStudy (cloverracer):

Oh I thought you meant in the problem haha. Yes it helps me visually thank you

OpenStudy (nikato):

ok if you know GI bisects <DGH, what do you know about <DGI and <IGH?

OpenStudy (cloverracer):

They share the same segment GI?

OpenStudy (nikato):

yes. but theres more. whats an angle bisector?

OpenStudy (cloverracer):

a ray that divides an angle into two congruent angles

OpenStudy (nikato):

correct. so that means <DGI and <IGH are congruent. got it?

OpenStudy (cloverracer):

yes

OpenStudy (nikato):

ok. and since you know <DGI=x-3 and <IGH=2x-13 you make them equal each other so you get x-3=2x-13 and you should be able to solve for x from here

OpenStudy (cloverracer):

x = -5

OpenStudy (cloverracer):

@nikato

OpenStudy (nikato):

No x-3=2x-13 -x. -x ------------- -3=x-13 +13. +13 ------------ 10=x

OpenStudy (cloverracer):

Oh what did I do incorrectly?

OpenStudy (nikato):

Idk. Do you mind showing ur work?

OpenStudy (nikato):

Maybe I could find your error
