Answer 1

The hypotenuse of the triangle can be determined as,

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

The cos A can be determined as,

`\begin{gathered} \cos A=(AC)/(AB) \\ =(8)/(9.43) \\ =0.8480 \end{gathered}`

The value of tanB can be determined as,

`\begin{gathered} \tan B=(AC)/(BC) \\ =(8)/(5) \\ =1.6 \end{gathered}`

Thus, option (D) is correct.
