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
If a=1 and b=2 , then 1+1=2 and 2>1. No it isnt possible to make the statement false because no matter what b will always be 1 greater than a
