i was thinking 130 degreees ?

OpenStudy (anonymous):

or maybe 115

OpenStudy (anonymous):

So what you do is you add up the two angles you have which adds up to 115. And since a triangle is always 180 degrees you subtract 115 from 180

OpenStudy (anonymous):

So then you know that the bottom angle is 65 so you see that the bottom line is supplementary so you subtract 65 from 180

OpenStudy (anonymous):

Do you get it?

OpenStudy (anonymous):

the asnwer is 115 right becase 130 woud be to much

OpenStudy (anonymous):

Yes but why

OpenStudy (anonymous):

im not to sure lol

OpenStudy (anonymous):

Do you know what supplementary means?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

Two Angles are Supplementary if they add up to 180 degrees.

OpenStudy (anonymous):

Okay so then you know that the outside angle and the one we just found out has to equal 180 degrees so you subtract 65 from 180 to get 115

OpenStudy (anonymous):

OHH

OpenStudy (anonymous):

XD ok

Yea Good Luck
