$$ - 1.008$$

$$\eqalign{ & \csc 4.8386 \cr & {\text{Use the reciprocal identity }}\csc \theta = \frac{1}{{\sin \theta }} \cr & \csc 4.8386 = \frac{1}{{\sin 4.8386}} \cr & {\text{Using a calculator into radian mode we obtain}} \cr & \csc 4.8386 \approx \frac{1}{{ - 0.992045}} \cr & \csc 4.8386 \approx - 1.008 \cr} $$
