U={1,2,3,4,5,6,7,8,9}
a={2,4,6,8}
b={3,6,9}

What is the set AUB?

AUB = {2,3,4,6,8,9}

Step-by-step explanation:

The set u should not be included in set AUB

99

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
