The answer is 223.75 because you multiply 12.5 and 17.9
Answer:
17
Step-by-step explanation:
The computation of the number of elements are in (A ∩ B) is shown below;
Given that
Set A contains 35 elements
And, set B contains 22 elements
Now if there are 40 elements in (A ∪ B)
So, the number of elements are in (A ∩ B) is
= 35 + 22 - 40
= 17
Answer=145
this is because supplementary means the two angles equal 180
180-35=145
