For number 2, I chose D. It was incorrect

OpenStudy (shaleiah):

For number 13, I put 53 it was incorrect.

OpenStudy (shaleiah):

For number 15, I put 36 it was incorrect.

OpenStudy (seratul):

For number 2, it cannot be D as both angles are not interior (in the inside.) Whenever two angles are not directly next to each other, are both in interior and exterior of the graph, and are on the same side, it is corresponding. So that would be C.

OpenStudy (seratul):

For number 13, when two angles are inside and are across from each other, they are the same length. A way that I like to see it is that if the angles are both larger than 90 degrees (or wider compared to others), they are the same measure. Same for angles that are less that 90 degrees. The answer would be 127 degrees.

OpenStudy (seratul):

Same concept for number 15, they are alternate interior angles so they must be the same measure. The answer for that would be 144 degrees.
