Jack is framing the roof of a structure using a triangle and two exterior angles.
Which relationships about the interior and exterior angles are true? Check all that apply.
A) a° + b° + c° = 180°
B) x° + a° = 180°
C) a° = c°
D) a° + c° = 90°
E) x° + a° = b° + c°
s i said inn the last problem you asked, the sum of the interior angles of a triangle always add up to 180 so option a is correct.
the base is a straight line so it has degree 180, therefore b is also correct. C is not correct otherwise this would be a rectangle. D is not correct, and niether is E.
Finally we have that A and B is corrrect.
