Answer:
2
Step-by-step explanation:
This question asks us how many angles are supplementary with 14. Supplementary means that the angle and angle 14 add up to 180 degrees, or a straight line.
We can tell that 13 and 14 are supplementary, because 13 + 14 = 180.
We can also tell that 14 and 15 are supplementary, because 14 + 15 = 180.
But since all the other lines in the diagram are not parallel, we can't make any more conclusions! The answer is 2.
