Answer:What are the equivalence classes of the equivalence relations in Exercise 3? A binary relation defined on a set S is said to be equivalence relation if it is reflexive, symmetric and transitive. An equivalence relation defined on a set S, partition the set into disjoint equivalence classes
The answer is 45 since every triangle is equal to 180 and angle 7 is 90 ,and the other two are equal you subtract 90 from 180 and divide the rest by two
The answer would be B, 1.7 and 1.8.
HOPE THIS HELPS! ^_^
18-23
The mode is the number/set of numbers that appear most in data.
In this bar graph, 18-23 is the highest bar as more students play 18-23 games per week than any other category, so 18-23 is the mode
