Find the union c1 ∪ c2 and the intersection c1 ∩ c2 of the two sets c1 and c2, where (a) c1 = {0, 1, 2, }, c2 = {2, 3, 4}. (b) c1 = {x : 0

See below.

Step-by-step explanation:

C1  = {0, 1, 2} and C2 = {2, 3, 4}.

C1 ∪ C2 = {0, 1, 2, 3, 4}       (Note: the 2 is not repeated in the result}.

C1 ∩ C2 = {2}.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
