Answer

$\cot$ (90$^{\circ}$ - 4.72$^{\circ}$) = 0.082566401

Work Step by Step

$\cot$ (90$^{\circ}$ - 4.72$^{\circ}$) 90$^{\circ}$ - 4.72$^{\circ}$ = 85.28$^{\circ}$ $\cot$ = $\frac{1}{\tan\theta}$ Therefore: $\cot$ (90$^{\circ}$ - 4.72$^{\circ}$) = $\cot$ 85.28$^{\circ}$ = $\frac{1}{\tan 85.28}$ $\frac{1}{\tan 85.28}$ = 0.082566401 Therefore: $\cot$ (90$^{\circ}$ - 4.72$^{\circ}$) = 0.082566401
