The first picture represents the elements in B that are not (also) in A. So, we want the set difference of B and A:

For the second picture, we can work like this: if we take all the elements belonging to A, we only need to add the bottom-right part, which is the intersection of B and C. So, we can express the blue part as

52°C is equal to 125.6 degrees Fahrenheit.
Given that 52°C it should be converted into degrees of Fahrenheit.
The celcius is represented by the letter C
And the degree Fahrenheit is represented by F
The formulas for the conversion are given by 
and 
Here the given is 52°C and we convert this to Fahrenheit by using the formula 
We have a C value is 52
By substituting the C value in the formula we get the F value

Hence 52°C to degrees Fahrenheit is 125.6

Answer:
C
Step-by-step explanation:
I took the test
The decimal approximation for the trigonometric function sin 28°48' is
Given the trigonometric function is sin 28°48'
The ratio between the adjacent side and the hypotenuse is called cos(θ), whereas the ratio between the opposite side and the hypotenuse is called sin(θ). The sin(θ) and cos(θ) values for a given triangle are constant regardless of the triangle's size.
To solve this, we are going to convert 28°48' into degrees first, using the conversion factor 1' = 1/60°
sin (28°48') = sin(28° ₊ (48 × 1/60)°)
= sin(28° ₊ (48 /60)°)
= sin(28° ₊ 4°/5)
= sin(28° ₊ 0.8°)
= sin(28.8°)
= 0.481753
Therefore sin (28°48') is 0.481753.
