Convert the angle 2π/3 radians to degrees.

11111nata11111 [884]

Answer:

2π/3 radians is equal to 120°.

Step-by-step explanation:

In this problem, we need to convert the angle 2π/3 radians to degrees.

The relation radian and degree is given by :

$D=\dfrac{180}{\pi}\times R$

Substitute all the values,

$D=\dfrac{180}{\pi}\times \dfrac{2\pi }{3}\\\\D=120^{\circ}$

So, 2π/3 radians is equal to 120°.
