how?
OpenStudy (anonymous):
or 168
OpenStudy (anonymous):
well how many degrees are in a triangle?
OpenStudy (anonymous):
okay its 118
OpenStudy (itsyacoolgrl):
180

because there are 180 degrees in a triangle. if you add 85 and 33 you get.. what?
OpenStudy (itsyacoolgrl):
108
OpenStudy (anonymous):
118. right. so then you subtract 118 from 130 to get the third angle of the triangle
OpenStudy (itsyacoolgrl):
whered you get 130 from?
OpenStudy (anonymous):
sorry. i mean 180. not 130

which = 62
OpenStudy (itsyacoolgrl):
Ooooh ok, Thank you :D
OpenStudy (anonymous):
so the third angle is 62
THEN, the line that branches off is 180 degrees. so you subtract 62 from 180 and get 118
OpenStudy (itsyacoolgrl):
So angle DAB = 62
OpenStudy (anonymous):
yes

\(x+85+33=180\) sum of all angles of triangle
and \(x+y=180\) supplementry angles
u need to find \(y\)
