Approx - 10%
72 students signed up for canoeing + the 23 students who signed up for trekking + the 13 students who signed up for both = 108 students
there are 120 students total, so you have to subtract 120 - 108 = 12
Now to find the percentage, you have to divide the number of students who didn't sign up for either, by the total
which is .1 = 10/100 = 10%

Answer:
alternate interior angles
Step-by-step explanation:
Alternate interior angles are the angles formed on the opposite sides of the transversal. Among these, the angles that lie on the inner side of the parallel lines but on the opposite sides of the transversal are known as the alternate interior angles.
For this case, from the diagram we can conclude the following results according to the surveys:
For Dogs:
Dogs = 24 + 31 = 55
No dogs = 10
Total = 65
For the cats:
Cats = 10 + 31 = 41
No cats = 24
Total = 65
