hold on

OpenStudy (anonymous):

118 i think

OpenStudy (itsyacoolgrl):

how?

OpenStudy (anonymous):

or 168

OpenStudy (anonymous):

well how many degrees are in a triangle?

OpenStudy (anonymous):

okay its 118

OpenStudy (itsyacoolgrl):

180

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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

OpenStudy (anonymous):

wait no

OpenStudy (anonymous):

DAB = 118

OpenStudy (mathmath333):

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