For each angle θ\displaystyle \theta in standard position expressed in radians, find its reference angle in radians to two decimal places.

(i) If θ=2.03\displaystyle \theta=-{2.03} then θ^=\displaystyle \hat{\theta}= 

(ii) If θ=5.18\displaystyle \theta=-{5.18} then θ^=\displaystyle \hat{\theta}= 

(iii) If θ=3.69\displaystyle \theta=-{3.69} then θ^=\displaystyle \hat{\theta}= 

(iv) If θ=0.92\displaystyle \theta=-{0.92} then θ^=\displaystyle \hat{\theta}=
