The reference angle is a positive acute angle. Angle 7π/6 in radians= = 7*180°/6 = 210°  ( because π rad=180°).
This angle is in the 3rd Quadrant and formula for the reference angle is:
x-180°.
210°-180°=30°
Answer: The reference angle for 7π/6 is 30°. 

Thee reference angle for 7pi/6 according to the task content is; 30⁰.

What is the reference angle for 7pi/6?

According to the task content; it follows that the reference angle of angle; 7pi/6 is required.

Upon conversion of the angle 7pi/6 to the degree measure; 7pi/6 = 210.

Hence the reference angle x can be evaluated as; x = 210 - 180 = 30⁰.
