Answer:
a. 8.7
Explanation:
We use the trigonometric ratio to find the value of AB.
[tex]\begin{gathered} \tan \theta=\frac{\text{Opposite}}{Adjacent} \\ \end{gathered}[/tex]
Therefore:
[tex]\begin{gathered} \tan 60^0=\frac{AB}{5} \\ AB=5\times\tan 60^0 \\ AB=8.7\text{ units} \end{gathered}[/tex]
The correct choice is A.
