Answer:
Here is the answer, I took it as simple I could.
F(x) = sin x
f(180/4) = f(45) = sin (45)
then , f(180/4) = 1/root(2)
Your answer is C, 66.73
First, we need to know which trigonometric identify to use, and we can choose tan because we are given the opposite and we’re trying to find the adjacent.
Then, because we know that
tan(angle) = opposite/adjacent, we can rearrange this to get adjacent = opposite/tan(angle)
This gives us 34/tan(27) = 66.73

Answer:
49% of the pupils are boys and 51% are girls.
Step-by-step explanation:
Alright, so first, you've got to find the total number of students: 567.
Now, to find the value of 1%, you divide 567 by 100, which will give you 5.67.
Next, you divide the number of male students by the value of 1%. That's 278 ÷ 5.67 = 49.0299823633157.
Subtracting that from 100% gives you 50.9700176366843 (percentage of girls)
Now, you can't write all that down, so you'll round it! 49.0299823633157 will round down, because 0 is less than 5, so it's 49%. 50.9700176366843 rounds up, because 9 is greater than 5, so that's 51%.
Therefore, 49% of the pupils are boys and 51% are girls.
I hope this helps!
