Question

Find the value of $\tan {240}^0$.

• A. $\sqrt{3}$
• B. $-1$
• C. $-\sqrt{3}$
• D. none of these

Answer 1

The correct option is A

$\sqrt{3}$

Calculate the value of $\tan {240}^0$.

$\begin{array}{rcl}\tan {240}^0& =& \tan \left({180}^0+{60}^0\right)\\ & =& \tan {60}^0[\because \tan (180°+\varnothing )=\tan \varnothing ]\\ & =& \sqrt{3}\end{array}$

Hence, the required final answer is $\left(A\right).$.
