Question

Which equation can be used to determine the reference angle, r, if 0=7 pi/12?

Answer 1

Answer:

$r=180-\frac{7\pi }{12}$

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

$r=180-\frac{7\pi }{12}$
