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
