So, say your # was 6,234,578. you would go to the seven and look to the number next to in, so 8, and if the neighbor is 5 or bigger, you make the number, in this case a 7 an 8. Last, you make all the other #s after the one you rounded 0. So the answer would be:
6,234,570.0
Answer:


Step-by-step explanation:
Calculate the value of trigonometry function.
and 
Split the angle between 0 to 90° using trigonometry formula.



Therefore, cos(480°) = -0.5



Therefore, sin(480°) = 0.866
It would be 19x because it is the same as 19 times x.
