Answer:
[tex]r=180-\frac{7\pi }{12}[/tex]
Step-by-step explanation:
To find the reference angle of a given angle, first of all, the quadrant of the given angle is determined.
So for 7pi/12
The quadrant is 2nd.
For the angle belonging to 2nd quadrant the equation for reference angle will be:
r=180 - theeta
[tex]r=180-\frac{7\pi }{12}[/tex]
