Use a calculator to find θ\displaystyle \theta to the nearest hundredth of a degree given csc⁡(θ)=−1.2139\displaystyle {\csc{{\left(\theta\right)}}}=-{1.2139} and such that θ\displaystyle \theta terminates in:

(i)  −450∘<θ<−360∘\displaystyle -{450}^{\circ}<\theta<-{360}^{\circ}, θ=\displaystyle \theta=  degrees.

(ii) 630∘<θ<720∘\displaystyle {630}^{\circ}<\theta<{720}^{\circ},  θ=\displaystyle \theta=  degrees. 

(iii) −90∘<θ<0∘\displaystyle -{90}^{\circ}<\theta<{0}^{\circ}, θ=\displaystyle \theta=  degrees.
