Question

1 What is the measure of (AB)? a. 8.7 b. 10 c.5 d. 2.5

Answer 1

a. 8.7

Step-by-step explanation:

We use the trigonometric ratio to find the value of AB.

`\begin{gathered} \tan \theta=\frac{\text{Opposite}}{Adjacent} \\ \end{gathered}`

Therefore:

`\begin{gathered} \tan 60^0=(AB)/(5) \\ AB=5*\tan 60^0 \\ AB=8.7\text{ units} \end{gathered}`

The correct choice is A.
