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
