Answer:
Reference angles are always acute.
We can find the reference angle with the "formula"
π
−
θ
, where
θ
is our given angle.
We can plug
5
π
6
into our expression to get
π
−
5
π
6
=
6
π
6
−
5
π
6
=
π
6
Thus, our reference angle is
π
6
It's 9. (I don't use inches in Canada but I made everything in inches so hopefully it helped)
