Answer

$\tan$(-80.1$^{\circ}$) $\approx$ -5.72974164

Work Step by Step

$\tan$(-80$^{\circ}$ 06') First, convert from minutes to degrees -80$^{\circ}$ 06' = -80$^{\circ}$ + $\frac{6}{60}$ -80$^{\circ}$ $\frac{6}{60}$ = -80$^{\circ}$ + 0.1$^{\circ}$ -80$^{\circ}$ $\frac{06}{60}$ = -80.1$^{\circ}$ $\tan$(-80.1$^{\circ}$) $\approx$ -5.72974164
