( A u B) would be the combination of both sets.
Since both sets have all distinct numbers, just add the 2 sets together.
4 + 7 = 11
There are 11 elements.
Answer:
CIM
Step-by-step explanation:
C is the 3rd letter of the alphabet, A is the 1st, and B is the 2nd.
CAB = 3,1,2
Repeating for DEK:
DEK = 4,5,11
Comparing:
4−3 = 1
5−1 = 4
11−2 = 9
BED = 2,5,4, so adding the corresponding numbers:
2+1 = 3
5+4 = 9
4+9 = 13
So the code is CIM.
Answer:
56°
Step-by-step explanation:
hii!
to solve this, we need to know that the angles of a triangle all add up to 180 degrees.
we are going to make an x equation here.
2x+3x+40=180
5x+40=180
-40 -40
5x=140
/5 /5
x=28
angle a is 2x, so the answer would be 28*2 which is 56°
hope this helped out :)
