Question

Express two pi over five in degrees.
A 30°
B 36°
C 72°
D 144°

Answer 1

The answer is the option C, which is: C.
`72degrees`

The explanation for this exercise is shown below:

To solve this problem you must apply the following proccedure:

1. By definition, you have that:

`\pi =180degrees`

2. Therefore, if you want to express
`(2\pi)/(5)` in degrees, you must multiply it by
`180 degrees` and divide it then by
`\pi`, as you can see below:

`(2\pi)/(5)=((2\pi)/(5))((180)/(\pi) )=72degrees`
