Which quadrant contains -11pi/18 and what is the reference angle?
1 answer:
Answer:
Option 1 is correct.
Step-by-step explanation:
Given angle . we have to find the quadrant and the reference angle.
Angle given is
Hence, the angle is 110° lies in second quadrant.
Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.
which is
Hence, option 1 is correct.
