OpenStudy (anonymous):

:)

OpenStudy (anonymous):

hellooo?

OpenStudy (anonymous):

what would be x+125 ?

OpenStudy (anonymous):

i dont know haha..

OpenStudy (anonymous):

it would be 180. so x+125 = 180. now find x. x=?

OpenStudy (anonymous):

55!

OpenStudy (anonymous):

correct. Now use some of angles in a triangle formula and find y.

OpenStudy (anonymous):

*sum not some

OpenStudy (anonymous):

Thanks, I have another question. If triangle ABC is congruent to triangle XYZ, AB=38, BC=28, and XY = 5X+8

OpenStudy (anonymous):

what is the Q?

OpenStudy (anonymous):

I just asked it haha

OpenStudy (anonymous):

If triangle ABC is congruent to triangle XYZ, AB=38, BC=28, and XY = 5X+8

OpenStudy (anonymous):

lol.. u did not. u need to fine X?

OpenStudy (anonymous):

I guess it isn't showing up, and yes I need to find X. :)

OpenStudy (anonymous):

okay. what is the meaning of congruency between two triangles?

OpenStudy (anonymous):

They're the same? idk..

OpenStudy (anonymous):

yaa. when they are the same AB=XY. so XY = AB = 38 so 38 = 5X+8 find X.

OpenStudy (anonymous):

6 :)!

OpenStudy (anonymous):

I have another problem lol :/

OpenStudy (anonymous):

good. thats correct. okay. post it.

OpenStudy (anonymous):

what do u think?

OpenStudy (anonymous):

C?

OpenStudy (anonymous):

try again

OpenStudy (anonymous):

I dont know.. could you explain?
