Answer:
C
Step-by-step explanation:
CB is congruent to AB because the both are 30 degrees
Answer:
solution:-We know that for any two finite sets A and B, n(A∪B)=n(A)+n(B)−n(A∩B).
Here, it is given that n(A)=20,n(B)=30 and n(A∪B)=40, therefore,
n(A∪B)=n(A)+n(B)−n(A∩B)
⇒40=20+30−n(A∩B)
⇒40=50−n(A∩B)
⇒n(A∩B)=50−40
⇒n(A∩B)=10
Hence, n(A∩B)=10
Step-by-step explanation:

Abcissa is x, and ordinate is y.
In this case the x is positive, and the y is negative.
Therefore, the answer is "positive, negative"
She can Hang up 4 posters. Because Taylor only has 16 tacks.
16/4=4
15=3b
15/3 = 3b/b
5= b
Isolate the variable by diving 3 on both sides
