Without using a calculator, compute the sine, cosine, and tangent of 330∘\displaystyle {330}^{\circ} by using the reference angle.

(Type sqrt(2) for 2\displaystyle \sqrt{{{2}}} and sqrt(3) for 3\displaystyle \sqrt{{{3}}}.)

What is the reference angle? degrees.

In what quadrant is this angle? (answer 1, 2, 3, or 4)

sin⁡(330∘)=\displaystyle {\sin{{\left({330}^{\circ}\right)}}}=  

cos⁡(330∘)=\displaystyle {\cos{{\left({330}^{\circ}\right)}}}=  

tan⁡(330∘)=\displaystyle {\tan{{\left({330}^{\circ}\right)}}}=
