Answer:
30
Step-by-step explanation:
is going to output a number in between 
and 
.
Luckily you are looking for 
in the 1st quadrant which is contained in the given interval above, so the answer just comes down to what the calculator returns from entering 
in your calculator.
You may also use the unit circle. sine value refers to the y-coordinate on there.
So you are looking for when the y-coordinate is 1/2 in the fist quadrant which is at 30 degrees.

I hope That I helped and I got my math right! You can just use a calculator!
Answer:
Given that
A = A ∩ S -- (1)
S = B ∪ B -- (2)
To prove:
A = (A ∩ B) ∪ (A ∩ B)
(A ∩ B) ∪ (A ∩ B)
= [(A∪A) ∩ (A∪B)] ∩ [(B∪A) ∩ (B∪B)]
=[A ∩ (A∪B)] ∩ [(A∪B) ∩ S]
=A ∩ (A∪B)
=A
Hence proved.
2) If B ⊂ A then A = B ∪ (A ∩ B)
R.H.S = B ∪ (A ∩ B)
= (B ∪ A) ∩ (B∪B) --(3)
As B is subset of A so
(B ∪ A) = A
From (2)
(B ∪ B) = S
(3) becomes
=A ∩ S
from (1)
A ∩ S = A
Hence proved
Answer:
There were 10 children in the group
Step-by-step explanation:
Here, we want to know the number of children in the group;
Firstly , we were told that the group contains 16 people
Secondly, we are also told that 6 of the people there are adults
and there are only two ticket types ( adult and children)
So the number of children will be the total
number of people in the group- number of adults = 16-6 = 10
