Answer:
The answer is d
Step-by-step explanation:
this is because a , b and c all have multiple x vales with more then one y value .
24+60=84>66
60+66=126>24
66+24=90>60
Therefore, the lengths are the sides of a triangle because the sum of lengths of two sides must be greater than the third side. All the sum of length of 2 sides are greater than the third side.
This is true sometimes and false sometimes, depending on the numbers.
