Question

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

Answer 1

`r=180-(7\pi )/(12)`

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-(7\pi )/(12)`
