hint : same side interior angles are supplementary

OpenStudy (ria23):

Have yhu figured it out yet?

OpenStudy (anonymous):

yes thank you :)i have one more question.

OpenStudy (ria23):

Angle 2 is opposite of angle 1, so angle 2 is going to congruent to angle 1.

OpenStudy (ria23):

have having that information, triangles always add up to 180, and the two sides are the same. yhu have angle 2 adding up to 140, and the other angle is going to be divided by two so yhu have the other angle making the triangle add up to 180. Does that make sense? :D
