Answer:

Option B. $tan(\frac{\pi}{3})$

Step-by-step explanation:

we know that

The tangent of angle ∅ is equal to divide the sine of angle ∅ by the cosine of angle ∅

$tan(\theta)=\frac{sin(\theta)}{cos(\theta)}$

Let

$\theta=\frac{\pi}{3}$

substitute

$tan(\frac{\pi}{3})=\frac{sin(\frac{\pi}{3})}{cos(\frac{\pi}{3})}$
