It has two adjacent angles that are supplementary, that is, they add up to 180 degrees.

OpenStudy (anonymous):

36 and 113

OpenStudy (danjs):

adjacent, means the same side, those two you said are opposite

OpenStudy (anonymous):

a=113 b=36

OpenStudy (danjs):

113 + b = 180 36 + a = 180

OpenStudy (danjs):

look at the adjacent angles part

OpenStudy (anonymous):

ok soo b=67

|dw:1419222345717:dw|

OpenStudy (danjs):

yep!

OpenStudy (anonymous):

a=144

OpenStudy (danjs):

Isnt that some thing used in geometry proofs, AB would be a transversal to the two parallel lines, and the adjacent interior angles are supplimentary

OpenStudy (anonymous):

yea

OpenStudy (danjs):

cool ...you got it

OpenStudy (anonymous):
