Answer:

The measure of the reference angle = 30°

Step-by-step explanation:

Convert 11[tex]\pi[/tex]/6 (radians) to degrees by multiplying by 180 and dividing by [tex]\pi[/tex]:

11[tex]\pi[/tex]/6 (radians) = 330[tex]\pi[/tex]/[tex]\pi[/tex] = 330°

Therefore, reference angle = 360 - 330 = 30°

First convert to degree from radian .

[tex]\\ \tt\hookrightarrow \dfrac{11\pi}{6}\times \dfrac{180}{\pi}[/tex]

[tex]\\ \tt\hookrightarrow \dfrac{1980}{6}=330°[/tex]

Find reference angle=360-330=30°

Last option is correct
