Answer:

3.8723

Step-by-step explanation:

[tex]sin(\theta) = \frac{1}{4}[/tex]

So [tex]\theta = sin^{-1}(\frac{1}{4}) = 0.25268[/tex] radians or [tex]14.48^{\circ \:}[/tex]

[tex]\frac{\pi}{2}} \text\;in\;radians=90 ^{\circ}[/tex]

[tex]\text{So\;} \frac{\pi}{2} - \theta = 90 - 14.48 = 75.52^{\circ}[/tex]

[tex]\tan(\frac{\pi}{2}-\theta) = \tan(75.52) = 3.8723[/tex]
