Find a counterexample to show that the statement is false. Assume all sets are subsets of a universal set U = {1, 2, 3, 4, 5}. (Enter your answers for A, B, and C in roster notation as a comma-separated list of sets. Enter EMPTY or ∅ for the empty set.) For all sets A, B, and C,

AU (B-C) = (AUB) - (AUC).
A, B, C = .

A = {1}

B = {2}

C = empty set

Step-by-step explanation:

REcall that given sets A, B then A-B = , recall also that the complement of the empty set is the universe set U.

Then,

Also, recall that given a set A, the union of A with the empty set is again the set A. Then

But,

i dont get the question

step-by-step explanation:

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
