At what values of x does the graph of f(x) = sin x intersect the x-axis?

I just took the test and got 100%

1: C, all multiples of pi

2: A, y= sin theta

   B, y= cos theta

3: C, y= csc theta

4: E, y= csc theta

   F, y= cot theta

These are 100%, feel free to mark as brainliest :)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
