If angle 2 measures 68 degrees, angle 15 would either measure 68 degrees (if they are corresponding angles) or 112 degrees (if they are supplementary and part of a linear pair). The specific relationship depends on the geometric context in which these angles are situated.
If angle 2 measures 68 degrees, and assuming that angle 2 and angle 15 are part of the same geometric figure, it's crucial to understand the properties of the figure. Since you haven't specified the type of figure, I'll assume that it involves parallel lines and a transversal.
If angle 2 and angle 15 are corresponding angles, which occur when a transversal intersects two parallel lines, then they are congruent. In this case, if angle 2 measures 68 degrees, angle 15 would also measure 68 degrees.
Alternatively, if angle 2 and angle 15 are supplementary angles, adding up to 180 degrees, and they are part of a linear pair, then angle 15 would be 180 degrees minus angle 2. Therefore, if angle 2 is 68 degrees, angle 15 would be 180 - 68 = 112 degrees.
The question probable may be:
If angle 2 measures 68 degrees, what degree measures angle 15?
