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=4.35\displaystyle \theta={4.35} then θ^=\displaystyle \hat{\theta}= 

(ii) If θ=2.51\displaystyle \theta={2.51} then θ^=\displaystyle \hat{\theta}= 

(iii) If θ=4.84\displaystyle \theta={4.84} then θ^=\displaystyle \hat{\theta}= 

(iv) If θ=0.28\displaystyle \theta={0.28} then θ^=\displaystyle \hat{\theta}=
