Question

Please help. Don’t understand

Answer 1

If the measure of the angle is 2π/3 the correct option will be tan∅=-√3.

What is trigonometry?

The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle are termed trigonometry.

It is given in the question that:-

The measure of the angle is = $\dfrac{2\pi}{3}$

We can also write the angle as = $\dfrac{2\times 180}{3}=120$

Now from the options, the only value which satisfies this angle is tan∅=-√3.

 $tan\dfrac{2\pi}{3}=tan \dfrac{2\times 180}{3}=tan(120)=-\sqrt{3}$
