Which quadrant contains -11pi/18 and what is the reference angle?

vekshin1

Answer:

Option 1 is correct.

Step-by-step explanation:

Given angle $\frac{11\pi}{18}$ . we have to find the quadrant and the reference angle.

Angle given is $\frac{11\pi}{18} i.e \frac{11}{18}\times 180^{\circ}=110^{\circ}$

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 $\pi-\frac{11\pi}{18}=\frac{7\pi}{18}$

Hence, option 1 is correct.
