#### Answer

$\cot$ 73$^{\circ}$ = $\tan$ 17$^{\circ}$

#### Work Step by Step

According to the Cofunction Identities $\cot$ $A$ = $\tan$ (90$^{\circ}$ - $A$) Therefore: $\cot$ 73$^{\circ}$ = $\tan$ (90$^{\circ}$ - 73$^{\circ}$) = $\tan$ 17$^{\circ}$ Therefore: $\cot$ 73$^{\circ}$ = $\tan$ 17$^{\circ}$
