Question

Which of the following are equal to 60 degrees?

Answer 1

Answer:

pi / 3 radian

Step-by-step explanation:

pi / 3 radian

= (pi / 3)*(180/pi) Degree

= 60°

Answer 2

Since 180 degrees are the same as $\pi$ radians, we have the following proportion:

$\text{radians angle}\div\text{degrees angle}=\pi\div180$

Since your angle, in degrees, is 60, we have

$\text{radians angle}\div60=\pi\div180$

Solving for the angle in radians, we have

$\text{radians angle}=\dfrac{60\pi}{180}$

Simplify this fraction and you'll get the answer.
