Answer:
Step-by-step explanation:
Given that there are 3 sets such that there are 100 elements in A1, 1000 in A2, and 10,000 in A3
a) If A1 ⊆ A2 and A2 ⊆ A3
then union will contain the same number of elements as that of A3
i.e. 
b) If the sets are pairwise disjoint.
union will contain the sum of elements of each set
c) If there are two elements common to each pair of sets and one element in all three sets
We subtract common elements pairwise and add common element in 3
i.e. 
4(-3x)=y F f f f f f f f d d d d d d d d d d d d d d d d d d d d d d
Answer:
40 degrees
Step-by-step explanation:
2x-30+x=90
Then you add x to 2x which will be 3x so now its
3x-30=90
add 30 to both sides
3x=120
divide 3 from both sides
x=40
Since Angle QPR is virticle to 2x-30+x=90
Angle QPR is 40 degrees
