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=4.61\displaystyle \theta={4.61} then θ^=\displaystyle \hat{\theta}= 

(ii) If θ=4.75\displaystyle \theta={4.75} then θ^=\displaystyle \hat{\theta}= 

(iii) If θ=2.3\displaystyle \theta={2.3} then θ^=\displaystyle \hat{\theta}= 

(iv) If θ=0.76\displaystyle \theta={0.76} then θ^=\displaystyle \hat{\theta}=
