Answer:
D. She only needs to know the measures of two angles, but one of the angles must be one of the remote interior angles.
Step-by-step explanation:
Because we don't know what kind of triangle we're looking at, and none of the lines are parallel or perpendicular, the other responses wouldn't make sense.
As a result, we'll need two perspectives.
C would not work since we would know that the two angles are supplementary if we knew A or B.
If we start with A, we'll end up with B, which is 180-A, and vice versa.
Both A and B are unnecessary.
