Respuesta :

The hypotenuse of the triangle can be determined as,

[tex]\begin{gathered} h=\sqrt[]{5^2+8^2} \\ =9.43 \end{gathered}[/tex]

The cos A can be determined as,

[tex]\begin{gathered} \cos A=\frac{AC}{AB} \\ =\frac{8}{9.43} \\ =0.8480 \end{gathered}[/tex]

The value of tanB can be determined as,

[tex]\begin{gathered} \tan B=\frac{AC}{BC} \\ =\frac{8}{5} \\ =1.6 \end{gathered}[/tex]

Thus, option (D) is correct.
