$csc$(-80.1$^{\circ}$) $\approx$ 1.45541868

Work Step by Step

$\csc$(-317$^{\circ}$ 36') First, convert from minutes to degrees -317$^{\circ}$ 36' = -317$^{\circ}$ + $\frac{36}{60}$ -317$^{\circ}$ $\frac{36}{60}$ = -317$^{\circ}$ + 0.6$^{\circ}$ -317$^{\circ}$ $\frac{36}{60}$ = -317.6$^{\circ}$ $csc$(-80.1$^{\circ}$) $\approx$ 1.45541868
