sad

OpenStudy (ayyookyndall):

Okay? Am I correct?

OpenStudy (anonymous):

its b

OpenStudy (bibby):

prove it

OpenStudy (anonymous):

simply 180-36 due to the parallel lines

OpenStudy (ayyookyndall):

Is this correct?

OpenStudy (bibby):

i think so, I can't remember the angle relationship formed along the Z's tho

OpenStudy (jhannybean):

Congruent angles along each base are equal to eachother, the angles that make up the sides are supplementary, so they add up to \(180^o\)

OpenStudy (anonymous):

as Z rule the other side of a=36 so a=180-36 the second choice
