@malcolmmcswain
OpenStudy (stuck-help):
a)X=15 Y=12
b)X= 14 Y=11
c)X=14 Y=12
d)x=15 Y=11
OpenStudy (malcolmmcswain):
Am I reading this right? 2x+7=12y+1

um...sorry idk wut dis is
OpenStudy (malcolmmcswain):
And by that, I mean are those equations both for the same line on the triangle?
OpenStudy (stuck-help):
(2x+7), (12y+1) and (3x-7)
OpenStudy (malcolmmcswain):
Oh wait, never mind.
OpenStudy (malcolmmcswain):
We're solving for the angles XD

i think so
OpenStudy (malcolmmcswain):
Ok, all we have to do is find which angles are congruent
OpenStudy (malcolmmcswain):
Which 2 angles are congruent?
OpenStudy (stuck-help):
the (2x+7) and ( 12y+1) i think
OpenStudy (malcolmmcswain):
Actually, those two are supplementary, so they add up to 180.

no (2x+7) and (3x-7)
and yes i got that after i said that so these two
OpenStudy (stuck-help):
so we need to find (2x+7)+(12y+1)=180
OpenStudy (malcolmmcswain):
Yup! So, we can set up an equation that 2x+7=3x-7
OpenStudy (malcolmmcswain):
Solve for x
OpenStudy (stuck-help):
x=14

and y = 12
OpenStudy (malcolmmcswain):

OpenStudy (stuck-help):
thank you and i will probably have a few more question
OpenStudy (malcolmmcswain):
I have to go though. Sorry! Good luck with your questions.
