8 in 2.408 is closer to 10, so you round 2.408 to 2.41
Answer:
Reference angle will be 30°
sin(330°) will be equal to 
cos(330°) will be equal to 0.866
Step-by-step explanation:
We have given angle is 330°
As the angle
is in forth quadrant
We know that in forth quadrant the reference angle is given by
Reference angle 
As the angle is 330°
So the reference angle will be 
Now we have to find the value of
sin(330°) 
And now 
The answer is A I believe
Answer is: Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 20.2
